In recent years, due to the global spread of explosive COVID-19, a large number of real-time, accurate and non-contact temperature measurement device/equipment has emerged, such as forehead thermometer, ear thermometer, infrared thermometer, temperature measurement security gate, etc. The rapid popularization and application of this type of product is due to the core component - infrared thermopile. It is equipped with a high-precision NTC thermistor chip as a temperature acquisition element, which effectively assists the infrared thermopile to measure the temperature accurately.

The infrared thermopile contains electronic circuitry for data calibration and output, which can be easily and effectively output temperature data by directly connecting to a microprocessor unit (MPU). NTC thermistor chip, as temperature compensation and temperature acquisition element, monitors the internal and external ambient temperatures of the infrared thermopile while also compensating the ambient temperature to provide temperature data reference.

The infrared thermopile uses the built-in NTC thermistor chip for temperature acquisition, and cooperates with other sensing elements inside the infrared thermopile for data collection, and finally feeds back to the terminal equipment through the microprocessor unit to achieve non-contact temperature measurement. In the virus-ravaged environment of today, safe, effective and rapid temperature data collection of infrared thermopile has been achieved, which has facilitated people's daily lives.

NTC thermistor chip used in the infrared thermopile is DT series NTC thermistor chip independently developed and produced by EXSENSE Electronics Technology Co., Ltd., which has high temperature measurement accuracy (can up to ±0.5%), which effectively improves the working accuracy of the infrared thermopile; Its fast response speed can complete temperature acquisition in short time, which can save time; It has wide temperature measurement range (-40℃~+200/250℃), in addition to human body temperature measurement, it is also suitable for industry, smart home, medical equipment and other fields.
