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 Alarm Circuit

The PIR motion sensor is a sensor which detects movement through picking up infrared waves. Being that a person emits infrared radiation, the detector is able to detect this radiation and react, according to the how the circuit is designed to react. Being that people naturally give off infrared radiation (heat energy), because of our generated body heat, the sensor can easily detect people ...
