MLX90615 Non-Contact Infrared Temperature Sensor Module Previous 
The OTP-N538U Thermopile Non-Contact Infrared Temperature Sensor is a thermopile sensor for infrared temperature measurement without contact. It uses infrared radiation to produce a voltage response at the output terminals. The sensor is built in a classic TO-46 housing and includes a blackened surface for absorbing incident thermal infrared radiation. Its active diameter is 545 μm. A thermistor element is also provided inside the TO package for ambient temperature reference.
