PIR Motion Sensor

PIR Motion sensor Layers overview

 







 







 






The PIR sensor power is 12V. Normally the PIR output is closed.  When no motion detected the output switch of the PIR is close and PIC get 0 (0V). Else PIC gets 1 (+5V).  






Magnetic Switch 

Magnetic switch for the system is pulled to high. When magnetic is close to the magnetic switch, the switch is closed and PIC will get 0 (0V). Else PIC will get 1 (+5V).
