Thermopile temperature sensor
Webb1 jan. 2014 · Introduction Thermopile infrared (IR) sensors are widely used as the sensing devices for non-contacting infrared (IR) thermometers [1] and non-dispersive (NDIR) gas sensors [2]. Devices fabricated using CMOS processes have good reproducibility, are mass producible and provide low unit cost [3]. Webb25 dec. 2024 · A thermocouple is a sensor made of two pieces of metal used to measure temperature. These two pieces of metals are welded together at one end, creating a junction where the temperature is measured. The above picture is a K type thermocouple available here at Seeed!

Thermopile temperature sensor
Did you know?
A thermopile is an electronic device that converts thermal energy into electrical energy. It is composed of several thermocouples connected usually in series or, less commonly, in parallel. Such a device works on the principle of the thermoelectric effect, i.e., generating a voltage when its dissimilar metals (thermocouples) are exposed to a temperature difference. WebbThermopile Sensors. Among Thermal Infrared (IR) detectors, our Thermopile Sensors are enabling many leading-edge non-contact temperature measurement applications …
WebbThermal sensors have a series of bimetallic junctions called a thermopile. Radial or axial heat flow through the sensor creates a voltage proportional to the power absorbed as it flows through the thermopile. The reading is not dependent on the ambient temperature since only the temperature difference is measured and not the absolute temperature.

Webb10 apr. 2024 · Thermocouples work by creating electricity when two different metals are heated up and can measure temperatures from really cold to super hot, making them perfect for industries like ceramics or foundries. Finally, thermistors measure temperature based on how their resistance changes, and come in two types: NTC and PTC.
