 And welcome everyone. I'm Jenny Wiley with Heritage Preservation. And we are so glad that you're joining us today. Kristen Lace, our Vice President of Collection Care Programs at Heritage Preservation, will also join us today. Let me go ahead and start by giving a quick introduction to the community and these webinars, and we'll move on to our next topic. Heritage Preservation is moderating the Connecting to Collections online community in cooperation with the American Association for State and Local History and with funding from the Institute of Museum and Library Services. The site is designed and produced by Learning Time. The goal of the online community is to help smaller museums, libraries, archives, and historical societies quickly locate reliable preservation resources and network with our colleagues. In developing the community, we have drawn on many resources that were developed for the C2C initiative, including the bookshelf and the Raising the Bar workshops and webinars. Links to these resources are filed under the topics menu on the site. We will also file a recording of today's webinar there. About twice a month, the online community features are a helpful preservation resource and hosts a webinar related to it. The resources we posted for today's webinars can be accessed by clicking this photo on our web page at www.connectingtocollections.org. Today, I am pleased to welcome back Rachel Perkins-Erinstein, a conservator in private practice. Rachel was kind enough to speak earlier this year on a C2C webinar about choosing a data logger. Today she'll take us one step further as we explore wireless data logging options. Rachel, could you tell us a little bit about yourself please? Thank you, Jenny. I am an objects conservator by training, but starting in my sort of former institutionalized experience and currently now in my private practice as a partner at AMR Conservation, I particularly enjoy preventive care projects, especially ones like environmental monitoring that involves fun technology and some cool gadgets. In addition to my private practice work, I also chair the Integrated Pest Management Working Group, which sponsors the Museum Pest Net website. And I'm the E-Editor for the American Institute for Conservation. And one of the organizing members of AICU's new collection Care Network, which provides support for cultural heritage professionals who are working in all areas of preventive care. And I hope that all of you on the call will start hearing more about the CCN and its projects through various venues soon. Thank you so much, Rachel. I'm going to go ahead and move over your PowerPoint. During the presentation, please feel free to type in any questions. And if we can't get to it right away, we will do our best to get to it towards the end of the presentation. Rachel, I'll go ahead and pass things over to you. OK. Well, it wasn't a surprise to me when Jenny's predecessor Elsa and I examined the reviews of the last webinar in data loggers. The big request was for a follow-up program on wireless systems. We all walk around now with our cell phones, and we seem to be able to beam all sorts of information to ourselves and to each other. So why wouldn't we want to do that with our environmental data? The technology exists, and there are products out there that are being used and marketed to the museum community. But we really need to examine carefully whether wireless systems work for us, or in this case, work for you, or whether your environmental monitoring needs are better served by a standalone data logger. Just because the technology's out there and because it's actually sort of cool may not be the best reason to go wireless. So the overarching message for today's webinar is really going to be some hard thinking about whether this is the right route. So I just want to get a few basics out of the way. For those of you who are on the last webinar with me on data loggers for museum monitoring, the focus is specifically on what I call standalone data loggers. And those are battery-powered devices that have a sensor to monitor conditions and a microprocessor that stores the information. And let's see. Tany, remind me, do you advance the talk please? I can do that, but you can also do it. There should be arrows in the lower left-hand corner. There it is. OK. There you go. OK. So thank you. So the standalone data loggers and wireless systems all have a number of things in common. These are battery-powered devices that have sensors to monitor the conditions and a microprocessor that stores the information. For a standalone data logger, each one works independently, and you have to download the data to view the results. But for today's program, we're discussing something slightly different. It's actually a sort of a misnomer to use the term wireless logger. Some of these systems, some of these units do log and store the information. But more appropriate would be to talk about wireless monitoring systems, because for the most part, these wireless sensors aren't really logging and storing the information, or at least for not very long. They're relaying it back to a collection point, whether that's the nearest Ethernet connection or a PC back in your office or lab. So let's take a moment just to find out what the audience is currently using. Denny, do you want to ask the first poll question? Sure. And maybe even the second one. Go ahead and pull these over. So which of the following equipment are you using to monitor? And then we also want to know, oh, I lost it. I also have to admit that when I saw the site for the posting on the Connecting to Collections online community, I sort of chuckled at the picture, because of course, what is being shown there is a nice picture of a Hobo U14 from onset, which is, in fact, a standalone data logger and not a wireless logger. So for any of you who've been looking at the website, don't confuse that with a product that we will be talking about today. Well, it looks like a lot of the answers are standalone data loggers, 70%. And then one or five spaces being monitored. I'll go ahead and pull these off. OK. So that's interesting and sort of more or less what I expected, given what we know generally about the Connecting to Collections online community. I've been asked also by the National Park Service to do another conservogram on wireless systems. They've been asking for a while, and I've been mulling over how to structure it, because it isn't as straightforward as examining and evaluating the standalone loggers. However, some of the parameters for any logging or monitoring system is still important. So I want to quickly run through those. I know that everyone wants to get to the products, but the products keep changing, and they'll continue to change frequently. So I think this information is really important in being able to evaluate any system from one that's out now to the next hot thing that will come out in a year from now. So some of the hardware specifications that you'll want to look into no matter what logger or wireless monitoring system you're using are going to include these parameters here. Operating range is pretty straightforward. This is the range of temperature and relative humidity over which the logger will work. So generally, most of the sensors, and certainly the ones that I'm going to talk about today, function over a temperature range beyond what we expect to see in our collection environments. So temperature is generally not an issue, but you do sometimes have to pay close attention to the RH range. Some of them will monitor from 0 to 100% RH in a non-condensing environment. But for instance, the T&D log EZ, which I'll talk about later, has an RH operating range of 15% to 90%. So if you're monitoring a case with archaeological metals and silica gel that you're trying to keep as dry as possible, or if you're in the Southwest where your conditions are extremely dry, you need to make sure that that parameter is going to be sufficient for you. Another thing that you want to just take a look at is accuracy. We all want to know that our data is accurate and some of these products are calibrated more carefully than others. Generally, everything we'll be talking about today is more than sufficient for our purposes. But remember, just like with any monitoring equipment, if you aren't checking the accuracy and the calibration every year or a couple of years, you can't have faith in the accuracy of your data. And so I believe in the resources that is on the website for this webinar, there's a sheet that was also given out at the previous webinar that my colleague Samantha Alderson and I wrote up on how you can check the accuracy of your loggers, a little system that you can set up with relatively easy-to-find materials. That will also be coming out probably later this year as a conservogram. So power source and battery life, this is something that I'll go over when we get to the product specific information. But some of these units are solely battery operated and others need to be plugged into a power source. So pay close attention to battery life to make sure that you're going to get enough power for your project and for however long. The ability to use a wireless system to relieve you of the need to download your data may not be as good a trade-off if you still have to replace batteries every six months. Sampling rate is how often the logger will take the data, the temperature and RH data or anything else that you're monitoring. In for wireless systems, you often have a sampling rate and then a transmission rate. If you're monitoring for general trends, you can be collecting data every 20 to 30 minutes. But if you're monitoring, let's say, the efficacy of your HVAC system, you may need more frequent reading. And so you need to just pay attention to whether you can set the sampling rate and if not, whether you'll be getting enough or too much data for your project. And the products we'll be talking about today run the gamut on that. Some of these systems have alerts and alarms on a LCD display like the standalone data loggers. And some of them also have the ability to email or text message you to send it to your phone. This is a great feature, but if you're not already or soon to be a convert to the smartphone, may not be a feature that you really need. Displays some of the, just like with the standalone loggers, some of the wireless loggers also have an LCD. But if the logger isn't in a place where you'll be able to view the readout, the display may not be a desirable feature for you because it certainly comes at the expense of battery life. Size, appearance, and construction is something just to take a look at. It's sometimes hard to tell this on the website. I tried to, for the units that I've played with and I had images of, I include a penny so you can get a sense of the scale. On the website, it's sometimes hard to know are they fist-sized, are they smaller, are they larger. The wireless units, some of them, the smallest is fairly small, like a fat candy bar. But generally, wireless units are a bit bigger than the standalone loggers. They tend to be anywhere, sometimes up to sort of like walkie-talkie size. So just something to keep in mind. One thing that's a different feature on the wireless sensors than on standalone loggers is buffering capacity. And this sort of I alluded to a little bit earlier. So wireless monitors don't always log, but it is a good and desirable feature if the sensor has the ability to store some data. And that's important in case your transmission is interrupted. Then the data isn't lost. It can be held by the sensor and sort of spent when the system is back online later. And so the number of sample points is something that you might want to pay attention to. And certainly cost is a big thing. That's something that very often I find most institutions that I work with, they often start off with a budget. Even before, they've really determined the project needs. They sort of know that they have a few thousand dollars to spend. And then it becomes a question of how do you want to spread that around? Do you need more sampling points or do you need more features? Standalone data loggers range from $70 to $700, depending on the features. And there are a few other ancillary costs. For wireless systems, you're going to pay more per sensor or data point. And there are some other costs to factor in. So determining your budget is going to help you clarify what else you might need to sacrifice for this capability. So those are some of the things that are sort of mostly the same. Let's take a look at some of the reasons why it can be great. The first is if you have lots of data. The wireless systems don't need cable or flash drive or a portable download device. They communicate without all those extras. So if you're using a wireless system, you can eliminate the time spent going around your institution and physically downloading the data. This can be hugely beneficial if you're in an institution that needs to monitor a lot of data points. And by a lot, I mean generally more than 20. And so for the most part, from the poll, I think that was most of you were well under that. We asked Jenny, that was the poll question on how many spaces or sensors you're currently monitoring. Our big space is 1 to 5 for the most answers and then quickly followed by 20 or more. So we do have sort of a split there. So if you're at 20 or more, the actual work of managing your data and getting around to collect those can become cumbersome. And so that's when looking at a wireless system that starts to maybe make some sense. The second is whether you need real-time data. It is sort of cool, and it's also super convenient to sit at your desk and click into your monitoring system to see what's going on. However, the main advantage to having real-time data is the ability to quickly learn and respond to problematic conditions in your collection environment. So if you're in an institution without climate control, you don't actually have the ability to make corrections. And therefore, real-time knowledge, while nifty, doesn't necessarily advance your collection care. So I'm going to emphasize this again. If you don't have an HVAC system, you probably need to have another compelling reason why you would want a wireless system. So let's ask the next poll question. Do you have the ability to control the environment in your space? OK, well, it's moving around a little bit, but it seems like the overwhelming majority of our attendees do have at least some ability. So that's good. OK, I'm seeing Michael from Atlanta saying some, but not all faces. And that's pretty standard as well. You might have it in sort of a new addition or in some of your special exhibition spaces, but not in all of your storage or all of your gallery. So it's just something to think about the cost of having that real-time data if you can't actually respond. One of the first places where I installed a system that had real-time data, we had a facility manager who was on his, had a beeper and responded to things 24-7. So for him, getting those messages in the middle of the night, he was going to be up and on that. If that's not something you can do, then all of that groovy technology is not being maximized. But one of the other compelling reasons to use a wireless system, especially if we're talking about an institution that may only have climate control in certain spaces, would be whether you have enclosed spaces that you need to monitor. So for instance, when I was at the American Museum of Natural History, one of the cases I had to monitor was that of what was called copper man. He was a mineralized mummy of an ancient Chilean minor. And the case was very tightly sealed. It was buffered with silica gel to keep the RH down as low as possible. And a single wireless monitor would have been great to know when I needed to open that case and recondition the gel. On a slightly larger scale, you could have a special exhibit based where the lender requests specific conditions and requires the case to be sealed after the courier leaves and something like a wireless transmission system. The case would allow you to monitor the microclimate without having to go in. So those would be some justification for looking at a wireless system. The next question, though, is whether you're really ready for wireless. So the questions that you need to ask are, do you have the budget? Again, the wireless systems are going to be more expensive than the standalone data loggers. Just like with the standalone data loggers, there's also a lot of wireless systems out there. And so in choosing the products that I wanted to talk about today, I tried to keep in mind that the connecting to collections community is geared towards smaller institutions. And so while there's a lot of products out there for advanced users, or components to make cool custom systems, that isn't what I thought was going to be most useful for this audience. So, Jenny, let's take a look at poll question number six. What is the most important criteria in choosing an environmental online rank system? I think that one is going to be something that maybe we'll take a look at at the end. So go ahead and feel free to type your answer. And this is actually one of our door prize questions. So we'll choose somebody at random, and you'll win a free gift. That should be to provide some incentive. OK, so we're seeing some interesting things here. Cost is coming up as a big issue. Ease of use, that makes me feel good about the kinds of things that we're going to discuss in a little bit. Data analysis. Data analysis, this is really interesting. Catherine from Atlanta. For data analysis, I have to say that this is not a strong suit right now for the wireless system. So Gretchen, who's in Pittsburgh, has a number of buildings over different spaces. And so that's certainly something if you have off-site where wireless is going to be a huge help so that if you don't physically have the ability to get to that space all the time. So just to, there's still more stuff coming in, but that's sort of the same kind of thing. So that's good. So in addition to having a clear idea of your budget and how much you're going to be able to get for a wireless versus a standalone system, you need to know whether you have the capabilities. So for some of the systems we're going to look at today, not all of them, but several of them require that you have a network within your institution. And so if you don't know what a router is or what it looks like, if you don't know what a LAN is, hopefully you have someone else in your institution that does. And if not, the wireless systems may not be right for you unless you're willing to delve in and really work your way through the instruction manual. So I'll give you an example. This is a Newport ITHX system. This is being used by a number of different institutions. They tend to be larger institutions. And if this sort of looks like a little scary to you with the wires and the probes and things sort of sticking out, if you aren't good with Excel, if you don't know what TCPIP packet, Ethernet LAN, or an SD flash card, means then this isn't the system for you. It's great. It's good to know that there's a lot other stuff out there beyond what I'm going to talk about today. But what I really am going to focus on for the most part are systems that are either plug and play, meaning that you can reasonably order them from the vendor or distributor, open the box, read the instructions, and get yourself set up. But I will talk about a couple of systems that are a little bit more advanced. And those do require a knowledgeable IP person in your institution. You need to be able to either get through a firewall. You need to be able to set up a static IP address. And within that parameter, there aren't actually that many good choices. There's a lot of stuff sort of out there. It's in the pipeline. But it isn't quite as polished as I think our profession has come to expect. So let's just quickly look at how many people sort of fall into this sort of second category. So Jenny, let's ask the next one to have an IT department or at least one staff member with experience in wireless or networking technology. OK. Well, so far it's looking good for those capabilities. People are still answering. OK. Well, that's good news for most of you. So before we sort of jump into the actual products, I just want to say that wireless doesn't necessarily mean that all the systems upload data to the cloud. Some of these systems are going to work off your internal network. And while the transmission is wireless, it's transmitting back to a sole point. And then in some cases, you can choose to make it web accessible. This is sort of important when you consider who needs to see your data. And ideally, there are a number of people in your institution who should be seeing your data. So that's another poll question that Jenny can ask you. Who else are you sharing your data with? Ideally, you should be sharing it with your facility administrator. And who else is it, whether it's your administration or your curator. If you love the capabilities of the old IPI PEM data site or the new eClimate notebook that they've rolled everything into, you may be better off collecting your data manually and sharing it in the cloud. So for instance, I just set up an institutional client in Massachusetts with some new monitoring equipment. And they only had the need and budget for five monitoring points. And they had very limited technological capabilities. So for them, in fact, a product like the PEM2 was more manageable. And I can log in and see the data from New York. And I can discuss it with their house manager and the chairman of the board, who's in a third location. So this is just one of these things to keep in mind whether you want to be sharing your data and do you want people to be able to see raw data, graphing, do you need to be manipulating those graphs, do you need to be comparing that. Those are some of the features that aren't so easily done on the wireless software products that we have to date. So OK, let's get to the meat of it now. And we're going to start with one of the products that's been out there for a while. This is the Onset Hobo ZWD to nodes. And this is really the first plug and play system that I came across. I think our field is broadly familiar with Onset. A lot of us are using other Onset Hobo products. And Onset has become popular with our profession because they have reasonable products at reasonable prices. And I think this is generally an example of that. The data nodes, you have one here with the internal sensors and one here sort of in the middle with the long cord, which has an external sensor. They take the readings and they transmit the data wirelessly to a receiver connected to your PC. So they log and wirelessly transmit real-time data. And each sensor will sort of transmit back to each other. And the sensors can act either as just sensors or as sort of sensor repeaters or routers, as they're called. So you develop what's called like a mesh network where the data can sort of go from one to another to get back to your central collecting point. They say that they have, when you read the wireless specs, they tend to talk about their transmission range. But it's important to note that for most of these systems, they're talking about a line of sight, like an unobstructed distance. So if they say transmission range is 100 meters line of sight, if you're setting that up in a place with walls, you've already cut down your transmission substantially. Some of the things that are nice features about the Hobo series is that they have, you can get alarm conditions via notifications, I think. And here, this is an image from one of their spreadsheets of what the alarms alerts beam to your iPhone look like. And here, you also have two views of the Hobo Nodes Manager, which is a module in the HoboWare Pro software. So on the left, you have sort of your floor plan view. And what you see there with all those lines going back and forth is how this sort of idea of the mesh network, how the nodes can transmit from one to another back to this collection point at the top of the screen. The image on the lower right shows you your Node Manager software. And then when you want to further analyze the software, you'd actually sort of open it up into the HoboWare Pro. So if you're using other Hobo products and you're happy and familiar with the HoboWare software, that's an advantage. You can get up to 100 nodes on a system, but really, you need a router for every 10 nodes. So that's something to pay attention to, because it's going to affect the cost of your system for every number of sensors. You need a router. So the system requirements, and I should tell you all now that I have a handout that lists all of the things that I'm going through now. These selected features, system requirements, potential limitations, and the general cost per sensor for each of these. So don't feel frantic if I'm going through this quickly. Denny is going to load this up along with the PowerPoint, so you'll be able to download that and have it for reference. So the system requirements for the Hobo node is that you need at least one data node, the data receiver, and the software is included. But depending on your deployment, you may need more of these routers. And so the sensors run about $250. The receiver is about $200. And the router is about $160. So depending on how far you can send your signal, that's going to determine the cost of your system. The difficulty is that you need to play around. And in my personal experience, that 100 meters line of sight drops down immediately in any kind of environment. I set the system up in my home. And I live in a typical timber frame construction. And I had trouble getting from my home office upstairs, sort of downstairs. So the thing that you know, it's really important for a system like this to understand that your budget may not go as far as you like if you need to be sending your signal across distances. The other thing that we should talk about are some of the things that will interfere with wireless communications. So the big issue is that your building fabric and construction will affect your wireless transmission. So some of the things that you need to think about are the actual positioning. But just knowing your overall construction may also help determine whether something like this is really in a practical way going to work for you. A lot of the vendors recommend that you don't place the units near metal building elements, which would be corrugated walls, floors, metal floors, and staircases. Buildings with concrete construction are going to be a problem. If you've got a lot of other wireless communications going on, if you're building management system, if you've got security systems that are working with wireless cordless phones, other wireless networks, that will interfere with the transmission of these devices. And then there's other sort of noise emitting sources, which can be various other electronics, and even things like fluorescent lamps. So all of these things are going to quickly sort of eat into whatever the manufacturer transmission rate is. And that's not just for the onset system. That's pretty much for all of them. So one of the things that becomes important if you're evaluating this is to sort of almost have to jump in, but expect that you may be forced to add on or be a little bit flexible with your budget in order to get the signal everywhere you need it to be. The one other thing to pay attention to with the onset hobo is that these must be plugged into a power source. They have a battery, but the battery is really a backup. And so it will last long enough, like for instance, to get you through an accidental power outage like we've seen with the heat in the storm. But this is, again, where you need to pay attention to that buffering sample rate. So for instance, the hobo nodes have a 4,000 sample memory. But if you are logging temperature and relative humidity, you already have to cut that number in half. So your 4,000 samples actually become 2,000 temperature and RH points. So if you're then monitoring, let's say every 15 minutes, that's going to give you 96 samples throughout the day. So you'll have plenty of memory to get you back on for a power outage, but it's not going to work as a battery powered unit. So that's just something to keep in mind when you evaluate. If you want to place these, do you have access to an electrical outlet or can you hardwire them already to a power source? OK. So the next product is something that is really brand new. And so the timing of this webinar was good, because if we had had it last month, I wouldn't have been able to talk about this. And in fact, I have to say that I have not actually played with this. The other ones, I have some personal experience. And so I'm waiting to get my demo unit, but I spoke extensively with people at MicroDac, which is one of my favorite distributors. And they're really excited about this product. And if you go to the last car website, they have a little five minute video on setting the logger up. And if you watch that, it's easy to see why MicroDac feels like this is going to be a really good product, especially for the kinds of users that we have in the audience today. This is also a plug and play system. The logger itself, which is this top right, it's a sort of a fist size unit. And it will log up to 500,000 readings. Again, you're going to cut that in half for your temperature on RH. And it wirelessly transmits the data back to your PC computer. It has this Groovy LCD, so you can see your battery status and alarm status in your current readings. It has things like the user selectable sampling rate. And the other thing that I really liked about it is that the sensors have a range detection built into the LCD. So when you go to sort of place them, you can walk around. And in a sense, you get the same sort of looking at what you would see on your cell phone, where it actually gives you on a scale of 1 to 10, 10 being full transmission and 1 being core. So it's very easy to figure out, as you go to place them, are you within range. The other screenshots that you're seeing here is basically you must have for this unit to work a functional Wi-Fi network within your institution. And so once you set this up, and essentially here on the left screenshot, you'd be picking which Wi-Fi system you're going to connect onto. And then you'd go to your next screen where you can set up things like your temperature and relative humidity alarm. And then once your systems are up and in place, you can look at them. You can sort of get your real-time data on a screen that looks like this. So you can see what's going on. You can check your signal strength, battery life, and alarm status, and all of that from your desktop. So again, the system requirements for this are really minimal. You need a PC computer. You need a functional Wi-Fi network. And you need to know your wireless key. And if you have that, then this also is a really easy system for almost anyone to get set up. So the limitations for this is that you may need a dedicated router if your security system, if you're working in a museum that has a security system that interferes with the logger communication. So if you've got a firewall and set up, and you're finding that you can't connect on, you could put up another router and get this set up fairly easily. Realistically, you can probably get up to 30 units on this kind of system. And beyond that, technically, you should be able to get more. But apparently, from what I've heard, once you go beyond 30, you start affecting the bandwidth. So the functional capacity of the system is a little bit smaller than what's actually in their product literature. As of right now, the system does not have email or text alerts. But that is apparently in the works. And they hope to have that added later in the year. So the cost for one of these sensors is $185. This is very cheap and is going to make this a really, I think, strong player in this market. So if any of you start looking at the system, I'll be eager to hear what your experience is. See what we have coming up next. Oh, sorry. So one more screenshot. This is the EasyLog Wi-Fi software. So what we have up in the top screen capture here is their nice visual way of choosing what portion of the data you want to be looking at on your time scale. And you'll see the graph looks pretty similar to what a lot of us are used to looking at. So it's a pretty nice piece of software at a very reasonable price. The next two products that I'm going to talk about are from a company called T&D. The T&D has been marketing heavily in the museum field recently. And their products have generated a lot of interest. I reviewed a couple of their products for the standalone data logger. And those are the ones that I was getting the most questions on because they are relatively new. And they do have some features that are sort of different. So first I want to discuss the LogEasy, which is also a plug and play system. And let me pull up the specs for that one. So you have sort of a graphical representation here of how it works. This is sort of the smallest of the sensors. It's sort of like the big fat candy bar size. And it's white and sort of unapproves of what you're seeing in the image with the logger is there's this sort of clear plastic piece that is a little flexible stand that you can plunk it in and will hold it with easy positioning. The thing that looks like a little flash drive is called a wireless dongle. And that needs to be inserted into your PC or laptop into the USB port. And it remains there. And so basically, your loggers are going to be transmitting back to that wireless dongle. They have a 50 meter line of sight transmission range. So the line of sight here is even less than what is on the system like the hobo nodes. And so again, for practical purposes, this is going to work best in small spaces or open spaces. And if you have even a setup like what they're showing you here in this diagram, you may need more because each of these, again, on this idea of this mesh network will communicate to each other. And so it becomes both a sensor and like a transmitter. So passing the data back to where it says office PC to that collection point. This is really meant to be a small system. You can support up to 16 of these log easy units and each access a repeater. They have a fixed 10 minute sampling interval. And again, this is one where there's limitation on the humidity measurements. They have a pretty limited buffering memory. And so a system like this, I think, would work really well in a special exhibition space. And you could even do it that you would walk through with your laptop on the dangle every other day and collect your data if you didn't want to be transmitting it all the way back. The starter kit, which includes the wireless dongle, a lager, and the stand, battery, user manual, software, and all of that is $159. And the additional sensors are $99. So this is a very reasonable price, but it's also a system that has some severe limitations. If you're in an institution where you have more technological capability aside, this is a glimpse of the log easy software that is logging from my children's bathroom, even as we speak. And it's very easy to download, see the graph in real time, which is the little box on the lower right, and then you download it into the graph. The graphing software doesn't allow you to do anything more complicated than really look at it and collect basic statistics. So if you really want to get into data analysis or something like this, you need to be moderately familiar with how to use Excel. So the next unit, the next system from TND is the RTR 500 wireless system. And this system has a lot of capabilities, but you need to have someone who's competent with networking solutions in your institution. Then there's a lot of different pieces on the screen, because there's a lot of different ways you can use the system. And that's one of its strengths. In the bottom right image, you have these four units here. The one in the top left is a handheld collector. The right are which ones are those? Those are the base station, one of which can work if you have a SIM card and a cell network. It will transmit over the cell phone service. And the other one is just a regular wireless base station. And then down below is a wireless ethernet base station. You can get that either in a wired or a wireless unit. The two other images that you're seeing here are what the various sensors look like. And the temperature in RH is this one here, which has the long probe. And the one that's in the middle, the sort of longer rectangular one with the orange window, that's one that has caused a lot of interest, because it also, that unit will be, the probes are not attached in this image, but that unit will allow you to also do UV and light logging. So one of the real drawbacks, these can function as standalone loggers. They can transmit optically or wirelessly. The big problem I had with them when I reviewed them for the standalone conserver grant was that the software was really difficult to work with. And on this screen, the bottom right is their old version of the software, which was the RTR multi-scale graph. And it doesn't look so bad here on the screen, but my colleague and I found it really difficult to manipulate the data to get a good graph out of it. They now have a new version of the software, which is in data mode. This is what you're seeing on the upper left. I have some issues with the pink, yellow, and gray, but that's actually easily changeable. And so their new software, I feel, goes a long way to addressing some of the concerns that I previously had about the system. But this is a bigger system. It's a lot more flexible. And if you have the technological capability to configure and launch the system, it can do a lot. However, it also comes at a substantially higher price, as opposed to looking at $1 to $200 for your sensors. Here, your sensors are anywhere from $340 to $500, depending on which unit you're looking at, just for the temperature in RH, or if you're also adding in the light loggers. And one of the base units funds anywhere from $400 to around $600. So your startup costs will be a little bit higher, but you can do more with this system. The last system that I want to discuss a little bit briefly is the handwall system. Handwall has really a lock on the whole wireless market for a really long time with their radio telemetry system. And what they have now, basically their products still work with radio telemetry. But instead of having to beam it all back to a central collection point, which often required that you spend a lot of extra money on repeaters, now you can beam it back to this sort of big box you see in the second image from the left, which is their smart reader too. So this will collect. You can put more than one of these in your building. And they will collect all the wireless radio transmitted data, and then that communicates over your LAN. It can be set up to just download on a scheduled basis or on request. And then you, as the user, would log in to your own server and see the real time or historical data there. The images that you're seeing, the sort of three on the right are some of the other kinds of add-ons that you can put onto the system. On the top left, you have your standard temperature and RH. And on the right, you've got one of the outdoor sensors. You've got the climate box, which also does CO2 if you're monitoring air quality. They have this new product called the Dustbug. So the handwell system, to start off with your FCC license, your software, and everything is going to start at $3,000. So this isn't a system for anyone who's really budget conscious, but if you're in a really large institution or you have some special need projects, this still is, although a high-end product one that people are using and some are happy with. So again, the handout is going to have this pricing information and the features and system requirements for you, as well as the list of vendors. So this just shows you have your different monitoring points. It's beaming back to your smart reader. And then you can access that from your PC. And you can have several smart readers all feeding to your server if you have multiple sites or locations. So just to quickly go back and review, we all know that environmental monitoring is now part of proper collections care. But it's not like once you get your monitor up, you get to just check off the box. You have to keep in mind what is the question you're trying to answer? Does wireless monitoring help you answer your questions? Are you spending more time analyzing your data if you get the wireless capability and knowing that even if you are moving into wireless, that you still need to take a close look at the product specs to match your product and capabilities of the product. It really does no good to go on the registrar's committee AAM list and say, what wireless product are you using? And do you like it? Because if you've chosen your product to match your project, you should be happy. And the trouble comes in when people aren't doing their due diligence. That said, don't forget that all of the products that I've mentioned here come from companies that provide very good customer support. Make sure that you've got your own in-house capabilities on board with what you want to do. And your own time and sanity should count for something and you can't get any systems set up. So I think I squeezed it in just under the hour. Were there any questions that are coming up that we need to answer, Jenny? We have a few on board, but before we get to questions, let me just go ahead and post our survey. It's very short. Please take the time to fill it out. We read everyone's responses, and it's so helpful. And so now, if you guys have questions, we'll just go over a little bit. We had a question a while ago about limited cell phone reception within the building and how that might affect a wireless system. Well, so for instance, if you have limited cell phone reception in your building, that could mean two things. One, it could mean that you would not want something like the RTR 500 data collector that works with the GCN that works off the cell phone system. But what it probably means is that you're in a building that has a lot of concrete or stone construction. So for instance, one thing that I know, if you go to the Met, they're very happy that you can't get cell phone services in the building. They feel like they don't want people talking on their cell phones that impacts the visitor experience. But the flip side is that you would know that that says something about your ability to transmit a wireless signal within your building. So that's going to mean that your system is going to become more expensive for the need to relay your signal more frequently. Or it means that you need to look at a system that allows you to quickly get back to the nearest ethernet port so that you're not trying to transmit it all the way back to a central collection point. Interesting, we also have Anne from New York who has a couple questions. One, about what happens when the laptop is closed or you're out of the office. So that's exactly, again, where this buffering memory comes in. For some of these products, the manufacturers will tell you your computer should always be on. Or if it's off, that's where you need to make sure that that buffering memory is going to be able to hold enough sampling points for how often you're sampling that it can store it in the memory. And then when you come in on Monday and power your computer back up, all of that will sort of flow down at that point. But if it doesn't have enough memory, essentially, you start losing that data. And that sort of deceives the purpose. And then also from Anne, wondering about the best recommendation for a unit in monsoon humidity, something of a topic. And that's a hard one. I guess, I'd have to think about that. And Anne, I'm happy to correspond with you after the webinar. Most of these sensors will work in these environments, just like any, whether it's a standalone or a wireless, the accuracy of your system is going to need to be checked more frequently in an extreme environment. I think the big question there is also, do you lose power on a regular basis? And if that's the case, is losing data a risk that you are willing to take versus having the real-time data? So let's talk about that more maybe on the C2C online website. So one other question about Anne Well, does that send alerts and alarm? Yes, it can be. If you're using that smart reader, too, it can be set up to do that. And then one more from Emma. We have the best unit or system for enclosed cases with no power source. So that's for something like the EL Wi-Fi system, this brand-new system I have really high hopes for. The LOG-EZ would be appropriate for that. But again, with the LOG-EZ, you're really only going to get a six-month life expectancy out of that single AA battery. You could also use the RTR500 system in a closed case, and you have a substantially longer battery life on that. But again, you need to be in an institution that has the capability to get that one set up. But that one, you could make the probe in, also make it really nice and small. But those would be your three options there. Do we have any more questions from the audience? And of course, any questions that we haven't gotten to or that you think of later, we can continue on the discussion board. OK. Well, thank you so much, Rachel. Thank you to our audience for participating. Again, please take the time to fill out this survey. We've listed up at the top left corner. We read all your comments. So thank you so much, and have a great afternoon. Thank you very much, Denny, Kristen, and Susan.
