HC-SR505 PIR sensor module

the hc-sr505 module is based on an infrared sensor or motion sensor sr505 and can detect the presence and movement of individuals from a distance of 3 meters. the operation of this small pir module is based on three pins: positive, negative, and signal. energy sources emit radiation, and the human body radiates energy in the infrared spectrum, allowing this sensor to accurately and reliably detect human movement.
