Qwiic IR Array (MLX90640) Hookup Guide
The Melexis MLX90640 (110° and 55° FOV) contains a 32x24 array of thermopile sensors creating, in essence, a low resolution thermal imaging camera. As the images show, you can detect surface temperatures from many feet away with an accuracy of ±1.5°C (best case). We’ve packaged the MLX90640 on an easy to use Qwiic board with mounting holes and a smattering of decoupling caps.
In this guide, we'll go over how to connect your Qwiic IR Array with MLX90640 and get it communicating with Processing to produce a nice thermal image.
We don't have any Qwiic shields available for Teensy, so you should snag yourself a breadboard and a breadboard friendly Qwiic cable if you haven't already to get the Teensy connected to the MLX90640.
Depending on your setup, you may need a soldering iron, solder, and general soldering accessories if you bought a headerless Teensy.
If you aren't familiar with the Qwiic system, we recommend reading here for an overview.

Since we'll also be using Processing in one of these demos, we'd recommend looking up the tutorial on hooking your Arduino up to Processing. We would also recommend taking a look at the following tutorials if you aren't familiar with them.
