Thermopile sensor
Application:
Non-contact temperature measurementProduct characteristics:
TO-46 metal packageDescription
The GT-511 sensor is a thermopile temperature sensor, which is made of hundreds of pairs of thermocouples connected in series based on MEMS technology. Using the Seebeck principle, when there is a temperature difference between the target and the environment, the sensor outputs a corresponding voltage, thereby detecting the presence of the target or the temperature of the target.
