The MLX90614 Infrared Thermometer Modules are intelligent non-contact temperature sensors that feature a single pin serial interface for connection to most microcontrollers. The MLX90614 sensors are designed for non-contact temperature measurements of objects placed within a sensor’s cone of detection. We offer two models: #28040 with a 90° field of view, and #28042 with a 10° field of view. Each sensor is comprised of an integrated ASIC and infrared sensitive thermopile detector. Each sensor communicates with an SX20AC/SS-G coprocessor over a digital SMBus, which Parallax has programmed to simplify an otherwise fairly complex communication protocol.
