What is a themopile?

Answer 1

A thermopile is a type of sensor that converts thermal energy into electrical energy. It consists of multiple thermocouples connected in series or parallel, allowing it to detect temperature differences and generate a voltage output proportional to that difference. Thermopiles are commonly used in applications such as infrared thermometers, gas appliances, and temperature measurement in industrial processes. Their ability to measure temperature without direct contact makes them valuable in various fields.
