(Passive Infra-Red) A PIR Motion Sensor is a motion detector sensor by measures changes in the infrared levels emitted by surrounding objects. It gives a HIGH signal at the I/O pin when motion is detected. Usually used as a security device in a monitored area (such as a room or hall) to detect the appearance of a human being.
