Thermopile Sensor RTTA71
Summary:
RTTA71 thermopile sensor is based on MEMS technology, consists of hundreds of thermocouples connected in series. Using Seebeck principle, when there is a temperature difference between the target and the environment, the sensor gives the corresponding voltage output, therefore detecting the existence of the target or the temperature of the target.
Feature:
* TO-46 metal package
* High sensitivity
* Quick response, Good stability
* High filter transmittance
* High precision NTC
APPLICATION
Due to the impact of the Covid epidemic, household body temperature products have been widely used. The forehead thermometer has ushered in vigorous development under the background of epidemic. At present, the shortage of infrared thermometers is about 60,000 units, and the shortage of handheld infrared thermometers is about 550,000 units in Chinese market. There is a great challenge for infrared temperature sensor companies, and it is also an explosive opportunity.
