 My name is Andrew Lindsay. I am basically a freelance developer. I have been working in a number of industries over the years, ranging from embedded systems, instrumentation, networks, e-commerce, retail, but always still go on and do IoT stuff. I like building sensors. We have heard earlier from people like Mike and Mark about the Things Network. Building global Internet of Things networks for sensors. What we have found is that there has been a lot of focus on actually building these networks, so people buying gateways. What we haven't seen a lot of is people building sensors, although what we have seen in sensors is things like this. They don't look pretty. They're not reproducible, or you've got manufacturers dev kits. They're not ideal for building mass sensors, and they're not really application specific or usable. I've been thinking about what to do, sort of go from things like breadboards to modules on Raspberry Pis to modules on Arduino's. I've been playing around with a few things in the past, river level sensors for the Flood Network in Oxford. This has sort of got me noticed by a couple of guys in the States. They don't build sensors, but they wanted to have somebody that would work with them and build sensors and develop these sort of things. Group called Healab, they're based out of Massachusetts, basically a little island called Martha's Vineyard. What they did to me is they said, why don't you come over and let's design some sensors, design a platform we can use. It was basically having a look where this place was, down near Boston, Massachusetts, and a big island, or a little island here. What I basically did, this might just look like a holiday snaps. Jumped on a plane and went over there to see the guys. What I didn't expect in April was four inches of snow, which was a bit of a surprise considering I've been in New York a month before. It was baking sunshine, but that's the vagaries of weather for you. It looks like a holiday snap, but basically touring around the States, down to Martha's Vineyard, across the ferry, and meet up with the guys there. I'm basically just sat around a table drinking beer. If you ever come across this beer, Dogfish Head 90-minute IPA, it is a very nice 9% ale. As far as I know, you can't get it in this country. We basically took a tour around the island. They were showing me where they wanted to put sensors in. We were going along back roads like this, full of puddles. We were visiting harbours because they were talking about shellfish beds, so they wanted to put sensors in the seawater. We were also doing a bit of a tour around some of the locations for the filming of Jaws. This was one of the harbours that was used. There's still more touring around the island. It's basically sitting down, looking out at the sea, discussing enclosures. If we're going to build a board, how are we going to enclose it, so it looks nice. Part of the tour around is where we're going to site gateways to cover the island. This is a place called Edgartown, and because it's April, there wasn't a lot of people around. Most of the population of the island live on the mainland and come here to their holiday homes in the summer. If you go there now, it'll be totally different. It gives us an opportunity to do a few pictures and also climb on the roof of a shop. These two here were views from the actual roof of a building where they want to site a gateway. We've actually got coverage over the harbour and the main ferry terminal into the island. There's also got a lot of the fisheries around the harbour there, so they wanted to put boys in the harbour there floating to get sea temperatures. They've got all these ideas, but it's how do we come to implement it? We're looking at the multi-tech mDoc board. It's a little XB type form factor module with built-in Lorawan, operates with the ARM embed system. One of the first prototypes on the top there in a plastic tube that was used in the greenhouse, just a test that we could actually do something. We started looking at other things we could do with it. We found some Arduino shields that work with some professional scientific quality probes for pH, for dissolved oxygen, so that they could be used in the sea water. What we came up with is a board that's about three inches square. We can plug in the multi-tech mDoc. We can plug in a series of sensors. All of these are just off the shelf that we can buy. We wanted to make it easy for people to build something. It's come through a few iterations, so we've got external temperature probes. We can plug on other external devices if the main hardware doesn't support it. I basically aimed to have one of these built and ready to demonstrate about two weeks after coming back to the UK. This was at a showcase in London for the IoT Meetup Group. We're showing the first prototypes of this module in a handheld form monitoring the state of a plant to go in for the agricultural use cases, even in a laser-cut case. We could try the enclosure options. Over the past few months, we've been refining the design and finalising the different use cases. Sitting around the table with people like Yodit and she's been firing ideas at me and saying, can you do this with it? Can you do that? There's been a few tweaks to add a couple of extra features. This is basically the final version that we've got at the minute. In this form, we can use it as a handheld device. I've had it here today, testing that I can actually connect into the Things Network Gateway down at the bridge rectifier. That was successful after it was restarted. Thank you, Andrew, for arranging that. The next alternative is an indoor sensor. Basically bare bones, sticking one of these temperature humidity sensors and a battery and that can sit in your house somewhere and you shared monitoring the temperature there in a nice little enclosure that was off the shelf. Another option is we can plug in this little PIR module and you can then do occupancy sensing in buildings under desks. What's the next one? Another option is to use something called the BME 280 which is a temperature humidity pressure module. It's a little plug-in board, put them in. All these little plug-in modules are made of root so it's basically off the shelf rather than going and getting something off eBay and then buying it the next week and finding that the manufacturer has changed even though it's the same supplier and finding that it doesn't work. So we've got something that can be plugged in and we know it's going to work if we buy it from a supplier in the UK, buy it from a supplier in the States. Next use case on this one was the shield from a company called Whitebox Labs based in Switzerland. They take two of these little modules that use the Atlas Scientific probes. These are the dissolved oxygen, pH, conductivity and ORP. You can then use this board in applications in aquaponics, in fish farms, monitoring your aquariums, and the aquafarming as well. You can also put on an external temperature probe using the screw terminals at the bottom to then get the water temperature. These are actually being used. The guys in the States here lab, they have been running a series of workshops over the summer. They're exploring all the use cases and getting the community engagement with this. The first one they did in July was with this company called the Island Grown Farm Hub, basically a massive greenhouse. There's some more detail in that in a little bit. But they basically had people come around, build sensors and apply them to the real application. The second one they did was people called the Polyhill Arboretum. This was the first of their STEM camps. They're actually putting sensors up in trees to monitor light levels right up in the tree canopy and soil moisture as well round the bases. The final one that was just last week was the Edgar Teng Great Pond Foundation, where they were doing some water quality monitoring to try and get an idea of are the fish going to survive, are the muscles, not the muscles, the oysters going to be grained correctly this year and generally monitor the water quality. Looking back at the farm workshop, it's basically big greenhouses, a lot of land, and they're growing all the food, salad stuff, because they're an island to bring stuff in, it's going to be expensive, so if they can grow a lot of the stuff there, that's going to be a bonus. So what they've got is all these greenhouses and they'd like to know the temperature all over them. Instead of going round and looking at individual temperature sensors or thermometers stuck up around the greenhouses, they'll have a look at using sensors. So they want to put in the sensors throughout the greenhouses and outside as well. So what the hill have done is they've got a number of people, they come round and they're basically going through the full sort of lifecycle developing sensors from basically first principles, prototyping them and then building up something in an enclosure and installing them on the sites as well. So they were using things like the multi-tech development board with the M dots, breadboard, the sensors that way. Get the data in through the gateways, program it using node red to feed the data into various locations. So then once they've got these out and boxed up, start to install them. So they had a range of ages from 11 to 56 on this camp. So basically they've got a number of these within the greenhouses and they can monitor the temperature and the humidity at different points. And then they've got a dashboard. It's just a fairly simple dashboard at the minute where they can see the different temperatures and the different zones of the greenhouses so that they can then get an understanding of what's going on in different parts. They're also looking at things like the soil moisture so they can know how things need watering or if they need watering more often. With all this, with myself working with Heal Labs, we also needed a few other partners and we've been partnering with multi-tech for the supply of the equipment. Also been partnering with Open Sensors and Yodit for the delivery of the data and the displays and also the guys at Whitebox Labs to provide the shields for the water quality sensors. Well, the future. We've got the board in a particular form. It's great. Build it yourself. We're going to start producing kits. We've had interest in building more projects around the island, not just the island, also the island of Australia. We've had interest from now, we've had interest from China. One of the big problems with this currently is it's not geared up for mass manufacturing because it's all through whole components. It's ideal if you want a kit, if you want to put it into an educational establishment, get people to build them up themselves. It's great. If you want to build 500 of these or 1,000 of them, it's very expensive. We've had quotes and it's basically said, yeah, we've got to go and build it up by hand or set up a jig to hold all the headers in place and run it through soldering machines. We need to do some redesigning. Version 2 is likely to be fully surface mount, probably more of the sensors built into the board itself. Partner Multitech are releasing a brand new module, obviously getting some samples next week, which is only available in surface mount form, so we'd have to go that way anyway, but it also reduces the cost of these boards as well. So looking at not just manufacture cost savings but overall parts cost savings as well to try and get this out and used in more places. Thank you. It might have been a bit quick there.
