TSEV0108L39 Thermopile Sensor Module SPECIFICATIONS Contact less Temperature Measurement 8 Measurement Pixels Wide Supply Voltage Range Digital Interface Bus (SPI) 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) SENSOR SOLUTIONS ///TSEV0108L39 Page 1 09/2015 TSEV0108L39 Thermopile Sensor Module FEATURES -20C +120C Measurement Range 4V 16V Supply Voltage Range Up to 2C Accuracy APPLICATIONS Contact less Temperature Measurement Microwave Oven Climate Control ABSOLUTE MAXIMUM RATINGS Absolute maximum ratings are limiting values of permitted operation and should never be exceeded under the worst possible conditions either initially or consequently. If exceeded by even the smallest amount, instantaneous catastrophic failure can occur. And even if the device continues to operate satisfactorily, its life may be considerably shortened.
