The PIR Sensor module allows you to sense motion. It is almost always used to detect the motion of a human body within the sensor's range. It is often referred to as "PIR", "Pyro Electric", "Passive Infrared", and "IR Motion" sensors. The module has an on-board pyro electric sensor, conditioning circuitry and a dome-shaped lens. The PIR Sensor module provides an output "High" when a human body is detected within its range and an Automatic Delay "Low" when the body leaves range. The delay time is adjustable using the potentiometer on-board. The minimum delay time that can be set is 4 seconds and the maximum of 200 seconds
