Motion sensors are widely used in various fields, such as sports science, medical health, smart homes, etc., providing us with many conveniences and innovations. The infrared sensor in the motion sensor detects the movement of an object by sensing the changes in infrared rays in the surrounding environment. When an object approaches the infrared motion sensor, the object will reflect infrared rays, and then the sensor will receive these reflected infrared signals to detect the movement of the object.
