SparkFun MLX90640 Arduino Example

========================================

  

   

   

  

  

    Qwiic IR Array (MLX90640-110x75 FOV) [SEN-14843]

    Qwiic IR Array (MLX90640-55x35 FOV) [SEN-14844]

  

This repo contains Arduino sketches that show how to output temperature data from the MLX90640 sensor. We've also included a Processing app in Example 2 to read in the values over the serial port and visualize them.



  



The MLX90640 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. We’ve written an example Arduino sketch and Processing app to get started with the sensor quickly!

The MLX90640 occupies a very interesting spot in the thermal imaging space. It is much higher resolution than the Panasonic Grid-EYE and much lower cost than the FLiR Lepton cameras. A very exciting advancement!

**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.

SparkFun labored with love to create this code. Feel like supporting open source hardware?
