The (often cross-referenced with the HC-SR501 ) is a high-performance passive infrared module designed for motion detection in security, home automation, and industrial systems.
Basic Logic: The Arduino monitors Pin D2. When the pin goes HIGH, motion is detected; when LOW, the area is clear. hw-416-b pir sensor datasheet
