The PIR Motion Sensor Detector Module HC-SR501 is a passive infrared sensor that is used to detect motion. It works by sensing changes in the infrared radiation emitted by objects in its field of view, such as the body heat of a moving person. When motion is detected, the HC-SR501 outputs a digital signal to indicate the presence of movement. The sensor is commonly used in security systems, lighting control, and automation applications to detect the presence of people and trigger an action, such as turning on a light or activating an alarm. The HC-SR501 features a compact size, low power consumption, and adjustable sensitivity, making it a popular choice for a variety of projects and applications. Featured By RoboticsBD.
