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.

Circuit Diagram for Raspberry Pi and PIR Sensor based Motion Detector As shown in the above schematic diagram for Raspberry Pi and PIR sensor based motion detector, the positive pin of PIR sensor is ...
