M5Stack Thermal Camera Unit MLX90640

The M5Stack THERMAL Unit is a thermal imaging camera expansion with a built-in MLX90640 thermophile sensor. This camera can be used to measure the surface temperature of an object and produce a thermographic image through a temperature gradient composed of different surface temperatures. The image resolution is 32x24 pixels. The MLX90640 infrared (IR) sensor array combines high resolution and reliable operation in harsh environments and represents a cost-effective alternative to more expensive high-end thermal imaging cameras.

This unit communicates with the M5Core via the GROVE A interface, the I2C address is 0x33.
