The MLX90640 Thermal Camera Breakout brings affordable thermal imaging to your Raspberry Pi and Arduino projects. With a 3224 pixel sensor array and 110 wide-angle field of view, it creates heat maps showing temperature variations across a sceneperfect for detecting people, monitoring equipment, or visualising heat distribution.

Measuring temperatures from -40C to 300C with approximately 1C accuracy, the sensor connects via I2C and runs at up to 64 frames per second for smooth thermal video.
