REDar - infraRed Radar

Using MLX90640 and ESP32, read an IR image of 32x24 pixels

Hardware Requirements

  • ESP32
  • MLX90640
  • Mac, Linux or Windows for programming

Software Requirements

  • ESP-IDF v4.0 (Probably works with other versions too)

How-To

This assumes command-line and ESP-IDF knowledge.

  • Install ESP-IDF on your system and set it up properly (source the environment & provide path to your USB device)

  • Wire the MLX sensor to ESP32 power and ESP32 I2C bus

  • SDA_PIN 21 & SCL_PIN 22 are defaults in this code

  • Clone this repo

  • Within this repo: make flash & make monitor

Program entry point

  • redar.c in main folder

What it does

Right now it only reads out cyclically the temperature array properly
