The PIR motion sensor has some advantages over other similar products: besides the low price, a signal is sent only if something moves. This allows you to wait for signal flanks using the GPIOs. In addition, a resistance can be varied so that a signal is only sent when the movement is close, or changes that are already far away are perceived. In addition to outdoor projects, the PIR can also ...

PIR stands for passive infrared. This motion sensor consists of a fresnel lens, an infrared detector, and supporting detection circuitry. The lens on the sensor focuses any infrared radiation present around it toward the infrared detector. Our bodies generate infrared heat, and as a result, this heat is picked up by the motion sensor.

This Arduino/Raspberry Pi motion sensor responds and moves, with the “strength” of movement controlled by an adjustable resistor (potentiometer). So you can set the motion sensor very sensitive, or try to avoid “noise”. As soon as something moves, a signal is sent that can be received and responded by the Raspberry Pi.
