Excellent specs and design, good value.

Somewhat off-topic, but if you want to get into thermal imaging for super cheap (albeit at a lower resolution again), you can get a compact FLIR kit from M5stack for $79 that's ready to use as soon as you charge it, but also freely hackable.

MLX90640-BAA is an interesting sensor.

Adafruit’s breakout sounds interesting, like enough for a homemade AIM9

This sensor contains a 24x32 array of IR thermal sensors. When connected to your microcontroller (or Raspberry Pi) it will return an array of 768 individual infrared temperature readings over I2C. . . . This version has a wide 110°x70° field of view we also have a version with a narrower 55°x35° field of view. . .

It's really low resolution, but I wonder what could be done with some super resolution techniques. Is the transfer function of these sensors well defined?

I don't know enough about thermal sensors to say with confidence and haven't looked up the spec sheet on this one at all. I'm just a fan of this manufacturer help them out with translation/documentation stuff occasionally. They market to prototypers and industrial clients and my experience is that their QA is good and they prioritize quality over lowest price.

Thanks a lot! That's super cool, very nice price tag, compact design, thanks for bringing it up :)
