THERMAL is a thermal imager Unit contains a thermopile sensors named MLX90640. It can be used to
measure the surface temperature of an object and form a thermographic image by a temperature
gradient composed of different surface temperatures. The image resolution is 32 x 24.
enviroments providing a cost-effective alternative to more expensive high-end thermal imaging
cameras.
Unlike the case of a microbolometer, the sensor does not require frequent recalibration,
for distances up to 7m. This Unit is 110°×75° FoV, also known as the BAA package.
The Unit communicates with the M5Core through the Grove A interface, IIC address is 0x33
