Infrared Motion Detector Circuit - Circuit Diagram ...

Note: – PIR sensor only detect the presence of the infrared rays which comes into its range, it does not emit infrared. Related Post: Simple Touch Sensitive Switch Circuit using 555 Timer & BC547 Transistor Working of Motion Detector Circuit. The PIR sensor typically operates at 5V, so we are using a positive voltage regulator IC 7805, which will give 5V output to feed the sensor.

How to Build a Motion Detector Circuit

The PIR motion sensor is a sensor which detects movement through picking up infrared waves. Being that a person emits infrared waves, the detector is able to detect these waves and react, according to the how the circuit is designed to react. The sensor can also pick up the movement of inanimate objects as well, such a rolling ball, because as those objects move, friction acts on them ...
