Definition of infrared sensor

Infrared sensor is a kind of sensor that uses infrared to process data. It has the advantages of high sensitivity. Infrared sensor can control the operation of driving device.

Infrared sensors are often used for non-contact temperature measurement, gas composition analysis and non-destructive testing, and are widely used in fields such as medicine, military, space technology, and environmental engineering. For example, the infrared sensor is used to measure the temperature of the human body's surface in a thermal image, and the abnormal temperature can be found.
