MLX90640 FIR Sensor

The Melexis MLX90640 is a fully calibrated 32 pixel x 24 pixel IR array in an industry-standard 4-lead TO39 package with a digital interface. The MLX90640 contains 768 FIR pixels. An ambient sensor is integrated to measure the ambient temperature of the chip and supply sensor to measure the V_DD. The outputs of all sensors IR, T_A, and V_DD are stored in internal RAM and are accessible through I²C.

These sensors address growing demands seen across numerous applications for thermal analysis. The sensor provides enhanced resolution while still occupying an attractive price point. Primary applications for this device include people detection, fire prevention, building automation, lighting control, surveillance, and air conditioning systems.
