TSEV0108L39 is a contact-less temperature measuring system for OEM use based on the detection of infrared radiation. TSEV0108L39 is equipped with an infrared sensor (Thermopile) in front. In this version a Thermopile Array, including 8 pixels, is used. It has to be pointed at the target object The basic working principle is: Detection of infrared radiation with a Thermopile sensor Determination of sensor temperature using a thermistor Calculation of ambient and object temperature using a processing unit Providing the temperatures at digital output bus (SPI like Interface)
