Thermoelectric infrared sensor chip
The company's thermopile infrared sensor is a sensor based on the Seebeck effect. The sensitive element inside the device consists of multiple thermocouple pairs connected in series. When the sensor receives external infrared radiation, a temperature difference is formed between the hot and cold ends of the thermocouple, generating a voltage signal that reflects the temperature value.
The thermopile infrared sensor consists of a thermopile MEMS chip, a 5-14um infrared bandpass filter, an NTC thermistor, and a miniaturized TO46 package. It provides an accurate voltage output related to external infrared radiation. Minshin thermopile infrared sensors can be used in non-contact temperature measurement (forehead thermometers, ear thermometers), household appliance intelligent temperature sensing and control, and air conditioning systems.
