This PIR V2.0 Switch Module detects the Infrared Rays released by human body motion within the detection area (6 Meters/20 feet).
PIR Sensor: A PIR Sensor is a Passive Infrared Sensor which controls the switching on/off when it detects a moving target. The PIR Sensor senses the motion of a human body by the change in surrounding ambient temperature when a human body passes across. Delay Time Adjustable: 5 seconds to 18 Minutes. Once the motion is seized it sends a "low" digital value to the digital IO port of your Sensor Shield.
