PIR Motion Sensor

A PIR Motion Sensor is a passive infrared sensor, which is used to detect whether people or animals are moving in its detection range. When the sensor is idle, the infrared intensity emitted by objects within the detection range of the sensor, such as rooms, walls and tables, is almost constant; When people or animals pass by, the infrared intensity
detected by the sensor changes. By detecting these changes, the sensor is able to determine whether people or animals are or have passed by. This sensor is often used in the security alarms, motion detection, intelligent switches and robotics. Note that the maximum detection distance of the PIR sensor is 3m to 5m, with an optimal detection distance of about 2m.
