You can now add affordable heat vision to your project and with an Adafruit MLX90640 Thermal Camera Breakout.

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. It's like those fancy thermal cameras, but compact and simple enough for easy integration. This version has a narrow 55 x35 field of view we also have a version with a wider 110 x70 field of view

This part will measure temperatures ranging from 40 C to 300 C with an accuracy of 2 C in the 0 100 C range .

With a maximum frame rate of 16 Hz the theoretical limit is 32Hz but we were not able to practically achieve it , It's perfect for creating your own human detector or mini thermal camera. We have code for using this sensor on an Arduino or compatible the sensor communicates over I2C or on a Raspberry Pi with Python.

If using an Arduino compatible, you'll need a processor with at least 20KB RAM a SAMD21 M0 or SAMD51 M4 chipset will do nicely. On the Pi, you can even perform interpolation processing with help from the SciPy python library and get some pretty nice results! This sensor reads the data twice per frame, in a checker board pattern, so it's normal to see a checker board dither effect when moving the sensor around the effect isn't noticeable when things move slowly.

To make it easy to use, we hand-soldered it on a breakout board with a 3.3V regulator and level shifting. So you can use it with any 3V or 5V microcontroller or computer.

We've even included SparkFun qwiic compatible STEMMA QT connectors for the I2C bus so you don't even need to solder! Just plug n play with any of our STEMMA QT JST SH cables. Even better We've done all the hard work here, with example code and supporting software libraries to get you up in running in just a few lines of Arduino or Python code.
