The MLX90614 Infrared Thermometer Module is an intelligent non-contact temperature sensor with a 90° field of view and a serial interface for easy connection to host microcontrollers. The MLX90614 sensor is designed for non-contact temperature measurements of objects placed within the sensor’s cone of detection. The sensor is comprised of an integrated ASIC and infrared sensitive thermopile detector. The sensor communicates with an SX20AC/SS-G coprocessor over a digital SMBus, which Parallax has programmed to simplify an otherwise fairly complex communication protocol.
