We have built a very simple Motion detector circuit here. We are using a HC-SR501 PIR Sensor, an LED (which will glow whenever there is a motion infront of the sensor) and resistor. PIR Sensor Based ...

The PIR motion sensor light wiring diagram is shown below. The basic idea is to amplify the output signal from the PIR sensor to control the relay, which, in turn, switches the bulb on or off. The ...
