Understanding Thermopile Detectors and Sensors
At the heart of thermopile detectors and sensors lies the thermopile itself. A thermopile is an apparatus that transforms thermal energy into electrical energy. It consists of multiple thermocouples connected in series or parallel. Each thermocouple comprises two dissimilar metals, creating a temperature gradient across their junctions. This temperature difference generates a small Seebeck voltage proportional to the temperature difference.
Working Principle of Thermopile Detectors and Sensors
Thermopile detectors and sensors operate on the principle of the Seebeck effect. When exposed to thermal radiation or a temperature gradient, the temperature-sensitive materials within the device generate a voltage proportional to the temperature difference. This voltage can then be measured and used to accurately determine the temperature.
