LM317T Voltage Regulator with Pass Transistor

This video demonstrates PIR motion detector with a pir circuitry. This circuit is a home made. The circuit uses pir sensor which detects motion and amplifies the signal. relay is switched on when motion is detected,and switched off when no motion is detected. The voltage regulator used here are,7805 and 7812 ic . i had assembled this inside a switch board, and connected to the mains 250 volts. as you can see when the relay is on, and off, light is on, and off. When a motion is detected the relay is switched on. This circuit is always on when continous motion is detected. It waits for a while before switching off. again when it detects a motion it is switched on. this project was designed and developed entirely by Titoo . they consist entirely of content that titoo created himself.. completed in 5 days.
