Description

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.

The MLX90640 Infrared (IR) sensor array combines high resolution and reliable operation in harsh environments, 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, ensuring continuous monitoring and reducing system cost.

The field of view (FoV) option includes a standard 55° x 35° version and a wide angle version of 110° x 75° 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

Thermal Camera Unit (MLX90640)

The cost of Thermal camera is well-spent money because I use it in my house on heater vent monitoring way up in the ceiling. The camera shows me the exact temperature I'm looking for. Great Product!
