PIR motion sensor HC-SR501

A motion sensor which can detect the heat from humans and animals, of the kind found in movement-activated lamps. The module is easy to use, simply connect power, ground and the output signal. When the sensor detects the movement of a temperature higher than the surrounding area it activates the output. Included are potentiometers for adjusting the sensitivity and time-delay. A jumper sets the sensor to "trigger" or "non-retrigger", meaning that the sensor either keeps resetting the output signal, or stays high continuously, during the movement.
