The output of PIR motion detection sensor can be connected directly to one of the Arduino (or any microcontroller) digital pins If any motion is detected by the sensor this pin value will be set to “1” The two potentiometers on the board allow you to adjust the sensitivity and delay time after detecting a movement.
