Parallax: MLX90614 infrared thermometer module

The MLX90614 Infrared Thermometer Module from Parallax is an intelligent non-contact temperature sensor with a single pin serial interface for connection to most 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. With a temperature range of -70°C to 380°C, auto-baud detection and a programmable alarm setting, this module becomes very useful in many applications such as surface temperature measurement, human/animal presence detection or HVAC. Up to 100 modules can be connected on the same bus making multi-zone temperature measurement easy.
