Description: Grove - IR thermal imaging camera MLX90641 110° - I2C - Seeedstudio 101020892.
The thermal imaging camera is equipped with a 16 x 12temperature sensorarrayMLX90641.It can detect temperatures from -40°Cto 300°C andobject temperatures from far away with an accuracy of ± 1°C in the center area and an averageaccuracy of ± 1.5°C.The camera communicates through the I2C interface. The camera's field of view is110° x 75°.

How does it work?
Each object emits a certain amount ofinfrared radiation. The IR thermal imaging camera is equipped witha heat sensorthat can detect small differences in temperature between objects in the environment. It then collects information about the radiation of objects and createsan imagebased on the information about the temperature difference. The warmer the object, the more IR radiation it produces.
The module communicates with the microcontroller via theI2Cinterface. For proper operation of the camera, a chip with at least 20000 bytes of RAM should be used. The camera operates withvoltage from 3.3 V to 5 V.On the board there is a Grove connectorfor easy connection of modules to the base plate.
