Infrared Thermopile Sensor is a non-contact infrared temperature
measurement detector. And the higher the temperature, the more infrared
energy is produced. Thermopile sensing elements consist of small
thermocouples on silicon chips that absorb energy and produce output
signals.

ISB-TS45H Infrared Thermopile Sensor is widely used in
non-contact temperature measurement. The sensor is packaged by the TO-46
metal socket, and the electronic components such as infrared filter and
thermistor are integrated inside, which has high reliability and high
sensitivity.
