A Passive Infrared (PIR) motion detector, commonly known as a PIR sensor, is an electronic sensor that is used to detect motion in its surrounding environment. PIR sensors are widely used in various applications, including security systems, lighting control, and automation, where they play a key role in detecting the presence of people or animals based on their body heat and movement.
