MLX90614 has something to with distance between sensor and subject. As far as I know, 2-3cm distance between subject and sensor will give you an accurate readings. It has an FOV of 90° so the diameter of the spot it will read is twice larger than the distance. That sensor will return the average temperature of all objects inside the spot.
Yup, I've seen in the data sheets that there are also a lot of other MLX versions that are medical grade or have fields of view that are lower than this. But I haven't actually tried anything else other than this hobby grade version of the MLX.
I did see a doc on the application of the amg8833 on social distancing, so for certain applications you could use it in combination with the kv210 so you'd have both a high res image and an ability to detect people based on their temperature. But if it's a wearable device, what would be the use case?
The amg8833 may not be the best choice to use for fire detection since according to the datasheet the max temperature it can detect is 80(100?) deg C. So you wouldn't know if it's a fire or a boiling pot of water. The amg8833 is normally used for people detection for automatic doors or airconditioning applications but it might be interesting to do research on how the sensor could also flag a situation where there might be a fire.
Hi:) I watched your video well. But I have some question. First, I plan to use lepton 3.5 for checking person temperature, and i want to know the specific temperature (like 36.5). In your video, you get that temperature. So can you help me how to i get that number only use lepton 3.5? Second, more detail , i want to get ROI(region of interest) average or pixel temperature.
I just used the average of the center of the image. I didn't really think of getting an accurate reading. So I'm not sure if that will really accurately reflect the person's temperature.
The lepton can provide the video data in a variety of formats. The one used here is RGB where the lepton itself maps the raw sensor values to rgb color which is just treated as a regular usb camera output. You can also get the data as a 16 bit number which corresponds to the temperature but it will require a some programming to get it in that format then it'll be up to you to convert the value to a temperature and also to a color that can be displayed. I still haven't done that yet though.
Oops, sorry, I'm not sure, I haven't had any experience with the leonardo. What I did try before was to use the arduino with the original lepton breakout board (through i2c and SPI). The problem was the original breakout board had problems and I couldn't get it to work without hanging. I looked at digikey recently and there seems to be a new version (the FLIR LEPTON BREAKOUT BOARD V2), but I haven't tried it out. Also the issue with the arduino is that it doesn't have the RAM to store one image frame from the lepton (the 80x60 pixel version would require storage for 4800 pixels) and I wanted to be able to store full frames.
Uh no I don't have the code anymore, but I used arduino for the mlx sensor. There's a lot of sample code on the internet. I just basically downloaded a sample and just tweaked it a bit.
Thanks very much for your sharing. I want to make a small therma camera for home inspection like water damage, air leakage and other thermal anomalies detection. But I am wondering whether lepton 3.5 Is suitable. Do you have some suggestions?
There are already existing thermal cameras for that. The reason you may want to use a lepton is if you're doing something specific like you can mount the lepton into a really tiny box on a stick and use it to inspect vents of places a normal thermal camera won't fit in. Or if you can program some specific image processing for it.
hello sir, right now im working on a thesis.and then, i use camera thermal amg 8833 and arduino. i wanna ask how to camera thermal connect to leptop. can i get your code for connect to leptop. can im consultation with you about my thesis?
I have tried to do this using an Adafruit itsybitsy M4 express with arduino but I can’t get the my python to read the data given by the THERMAL CAMERA.
digikey.ph Not sure how much this is today but i got it at around $200+usd a few years ago for the camera unit and control board. You'll need a lepton camera unit and the control board (type depends on how you want to use it)
Technically these can detect temperature variations more than that distance as I've tried the lepton outdoors but if you need accuracy (like detecting if someone has a fever) I think the accuracy will drop the farther you are from the sensor.
@@garciamelaiza5334 The lepton can capture images farther than 5m but I'm not sure about it's accuracy at that range. The specs say it's +/- 0.5 deg C but there's no mention of the effect of distance.
@@animocapvids okay thanks for your reply it means a lot to use .... btw the idea in Infrared thermometer automatic measuring & voice system - Arduino th-cam.com/video/O1LYi0Sg5SE/w-d-xo.html we use it but our professor wanted to detect more than in a distance and I have an idea to that and also to my groupmates
That would only see "Near Infrared" (which is still cool in it's own right, I'm building a portable camera using it), actual thermal imagers use "Far Infrared" where you start "seeing" temperature with sensors like these (which I kinda wanna add to my Near IR camera since I'm using a Pi 3 that could easily run both for even stranger capabilities for my project)
Yes it will. But when I tried it before, I just downloaded a generic app for USB webcams for android. It did work, showing the thermal camera view. But if you need to use it to show temperature info you'll probably need an app that supports the lepton connected via USB. I didn't find any then so I planned to build one in android but I never got around to doing it.
Oops sorry I didn't make any sort of documentation for this, but you can get a lot of schematics and tutorials for using these components on the web. I just follow tutorials from sparkfun and adafruit myself :-)
I'm trying to create a "cheap" presence detection for ex when a person is present and not moving watching TV. Would you recommend a cheap sensor for monitoring 4x6m rooms?
@@Airbag888 The amg8833 is more expensive maybe 4x more than the mlx90614. That's because it's an 8x8 pixel sensor while the mlx is just a single point. So if you're covering a wide area you'll need a sensor that can cover the area.
I wrote a program in the arduino to output the data through serial, then used a program in visual c++ in the pc to display it. For the pc side you can use any programming language that can read serial input and display graphics.

I think their other larger boards have both a usb to connect to a pc and also pins that you can use to connect to a microcontroller if you plan to use those. Good luck on your thesis!
It has an SPI interface (using the breakout board) so you could connect it but you need at least 4800 bytes (plus extra) to buffer the image so an arduino won't be able to handle it.
Hi sir, I am working on my FYP can you suggest to me any of these for detection of body temperature under the distance range of 5-6 feet and also with good accuracy.
