Rokonet Risco IrexPlus Request to Exit PIR Motion Sensor with Internal Buzzer and Relay Timer

[Music] hey guys in this video I am going to show you how to troubleshoot PIR motion detectors and get it working properly PIR sensors detects or read infrared radiation emitted from objects around it is view range and give output signal so here is the circuit here I used nine volt battery and seven at zero v IC to supply a 5 volt regulated voltage to sensor and I recommend you to use this IC because one of the recent PIR sensor gives false output is this it require regulated constant voltage and it can be seen that it works perfectly on 5 volt so no need to give more than that detector has three pins VCC where we do 5 volt supply through 7 at 0 v IC output pin it basically sends high signal of nearly 3 volt when the motion is detected and sends zero volt signal when there is no motion and then I have used transistor as a switch so whenever a detector detect the motion it sends high sig
