What Is a Thermopile Sensor?
A thermopile sensor is a device designed to detect infrared radiation and measure the surface temperature of objects without direct contact.
This sensor features an array of thermopile elements—thermocouples—that measure thermal radiation to determine temperature. It incorporates optical elements that focus on infrared radiation, allowing it to detect specific wavelength ranges of infrared light through the use of optical lenses and filters. This capability facilitates the non-contact measurement of object surface temperatures.
Thermopile sensors are utilized in various applications, including thermometers and infrared thermography for thermal imaging. They serve multiple purposes across different sectors, such as in household thermometers, industrial temperature monitoring, and detecting anomalies in buildings and machinery.
