Pir Motion Detector Circuit Diagram. In this circuit pir passive infrared motion sensor is used which is used as a motion detector. This can also used in automatic room light when any person enter in the room then light automatic turn on and turn off after fixed time.
In this circuit pir passive infrared motion sensor is used which is used as a motion detector. Such detectors are widely used in industrial commercial and residential building automation applications see ti reference design tida 01398 for more system information. Infrared pir human motion sensor detector modules.
The ir sensor will make the high frequency beam of 5 khz with the help of 555timer which is set to astable multivibrator mode at the transmitter section.
In this circuit pir passive infrared motion sensor is used which is used as a motion detector. The passive infrared sensor consists of three pins as shown below. Universal pcb and more parts. This can also used in automatic room light when any person enter in the room then light automatic turn on and turn off after fixed time.
