 All right, this week's Eye on MPI is from Sincerion, Lady Eda. What is this week's Eye on MPI? That's right. I'm kind of a sucker for Sincerion sensors because they're always really good and I really like sensors. So I want to show you the kind of the newest, most interesting things. And this sensor is interesting. It's a low pressure flow meter. It's kind of intended for medical uses, but I actually think it could be useful for a lot of robotic or industrial uses where you want to measure air flow, but you want to be able to handle like low flow rates because a lot of sensors that we've got are intended either for water or for high flow rates because they create some pressure. This one is designed for medical uses such as like a CPAP or a ventilator. But even if you're not doing medical grade stuff, I think this is an interesting sensor. So this is the SFM, sorry, SFM P119. It's a low flow air or gas, the non-crosive air or gas sensor. And it's meant for non-liquids, meant for gases. It's tuned for either air or oxygen, but you could probably tweak it for and calibrate it for other sensors. What's nice about it is it's low cost. It's really simple and it's kind of all in one. It's got a flow rate range. I can't remember. Maybe you can go this way. I can actually read the text. Oh, yeah. Yes. I can do that. You can go up to 240 SLM, which is leaders, standard leaders per minute. And yeah, the design of it is very modular. Like a lot of sensors we've seen that are for this are designed for like one customer. This is kind of designed for anybody to use as long as you can just connect to either side. It's small. It's plastic. There's an inlet and outlet. It's monodirectional, so gas is only supposed to go one way, but it looks like it can handle some negative flow measurements, perhaps not precisely. There's O-rings on either side. You can see the directional knob and there's a little module on top. It's quite small. Only maybe two inches by one inches by two inches or so. And this is what our liquid flow rate sensors are like. This is kind of a low-cost turbine sensor, and so you can see that there's a little turbine in it. But if we go to the overhead real fast, I can show that this sensor doesn't have a turbine. I actually don't know how it works. I didn't do a ton of research. I didn't want to take this apart because I had this working, but it could be some sort of capacitive sensor or something. I don't know. It's a little bit mysterious. But you can see there's no turbine, so the gas or air flows through without anything impeding it, which can be very good for low flow rates. Another thing that I really like about this is a lot of flow rate sensors use Hall Effect sensor on the turbine or something, and you have to count. You have to calibrate it. It's not quite linear, whereas this sensor has a standard I-squared C interface. You just power it with three to five volts. You get clock data at ground. It's on a two millimeter pitch connector. It's a standard connector. I just used a two millimeter pitch wire connector that I had handy and plugged it in to get it working, and it just works, and you can query it and get data, and it's all ready to go. It's all pre-formatted temperature and flow rate data. There's also check sums, which I always like, means that the data you're reading you can verify, especially if you are using this for medical uses or important uses, like making sure that there's enough oxygen or air flow in an area. It's good to make sure that the data you're getting is verified, so having a check sum is handy. The good news is you don't have to do any of the coding yourself, because they've actually released libraries. This is just one library. This is the Arduino library, but they have a Python library. You've got an embedded C library. I think they have one for a couple different ... They didn't have four or five different libraries in different languages that are ready to go with an example code that you can read temperature and flow rate. Actually, I was able to wire up the sensor and have this demo. I got it up and running in less than 25 minutes. It could be easily integrated almost immediately. I always like that, because I feel like you get a sensor, and especially low-cost ones that are not calibrated. You don't trust them. You have to do a lot of setup. You have to test them in all these situations. I like that this one just gives you digital data. You don't have to do any linearization or modeling of the sensor at all. There's lots of documents. There's step files for the 3D model. There's handling information. There's different calibration details of how they calibrated it for oxygen versus air or a mix, I think, of oxygen and air. Pretty much, it was just really, really fast to get going. I can show a demo real fast, and then we can show a demo. This is the sensor, so I just had a two-millimeter pitch connector, and I wired it up. You see that there's a little filter here to keep dirt and dust out, but it's a very fine filter, so it's not in the way. Then this arrow shows you which way air flow goes. Right now, there's no air flow. You're just reading the temperature. It's a little warm here under the lights. But if I blow into the sensor, yes, the flow sensor, I don't have an O-ring. I'm not putting my mouth on that because it would be gross. But just blowing through the sensor, it detects my air coming out of my mouth, and it responds very quickly. It does have a low-pass filter built-in that I think it's enabled by default, but you can disable it, but it's probably a good idea because I think air flow, especially, can be very buffety. Then you want to have a couple readings in a row that are averaged out, and it does that for you as well. Available on Digi-Key? Shortly. So when I purchased it and it was in stock, and then as I was writing an MPI, I looked back and it sold out. However, they're going to get another shipment. It's rare. Usually they don't sell out, but this is a pretty cool sensor. Very handy, and the price is quite good for a sensor of this grade and usability, only like about $120. So it'll be in stock in about two months. Also, contact Digi-Key if you need them immediately, and they can hook you up with samples from since Syria. And it's usually, this is an unusual situation, but high demand. You know, there's videos that a lot of sensor makers have. And some of them are okay. I like this one a lot. So that intro from the show will all make sense now. I will say that this video is for the SFM series. They talk about other sensors that are in the family, not just this one. So it'll look a little different. But it's about how these sensors in general work. So it's still a very good video to get an idea of what it does. They do a good job. So we're going to play the whole thing. And there's a teddy bear. It's about two and a half minutes. The teddy bear lives. Hi, and welcome to the Sensorion Flow Sensor video series. I'm Grisha, a contact partner for our valued medical customers. This video in our flow sensor series is all about proximal flow measurements. I'll go through a few of the challenges in this field and show you our sensor solutions. Proximal flow measurements have the big advantage that they are unaffected by leaks in the tubing system. Sensor readings offer direct feedback on how much air the patient is inhaling and exhaling, which is very useful. Even so, harsh operating conditions can put accuracy and reliability at risk. Changing temperature and humidity levels are common, especially in an emergency and transport setting. In addition to that, proximal flow sensors are in contact with pathogens exhaled by the patient. Thankfully, there is an answer to these challenges. The Sensorion SFM 3300 and 3400 series. The flow sensors are designed for use with adults and infants alike and are available in two versions, reusable and disposable. The former can complete up to 30 autoclaving cycles, while the latter offers the same measurement performance at a lower cost. For ease of use among medical personnel, we have fitted all of our proximal flow sensors with grooves for a clip-on connector cap. Connecting them to breathing circuits with their standard medical cones is easy too. Want your proximal flow meter to be heated to prevent rainout in humid environments? No problem. We've made sure to equip them with a small heater. The digital sensor output is factory calibrated and compensated for temperature variations. If you want to perform first tests, look no further than our evaluation cable, which you can order from our distribution partners. And to visualize and log data recorded by the sensor, we provide free readout software. Our website and info line are waiting for you. Thanks for your interest in our flow sensors. See you again in the next Sensorion video.
