Introduction
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.
Required Materials
Not Uno Compatible: The MLX90640 requires complex calculations by the host platform. A regular Uno doesn't have enough RAM or flash to complete the complex computations required to turn the raw pixel data into temperature data. You will need a microcontroller with 20,000 bytes or more of RAM. We recommend a Teensy 3.1 or above. Make sure to grab headers if you get a headerless version of the Teensy.

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.

Suggested Reading
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.
