220v Motion Sensor Circuit Diagram. This circuit scares me a bit because Im used to working with 9v 6v and less. The schematic diagram of this circuit is.
The circuit can be modified for various applications including AC operated alarm systems. Parts Needed for Motion Detector Alarm Circuit. PIR Sensor is high sensitive With Any MotionMovement of Anything Around This Range.
PIR Sensor Based Motion.
We connect pin 1 of the PIR sensor to 9VDC and we connect pin 3 of the sensor to ground. Schematic of the Motion Detector Circuit. The Vcc pin of Sensor Is Connected with 5v Dc Ground Pin Is connected With Negative DC Supply And Output Of Sensor Is Connected With BASE Of NPN Transistor Here BC547 Is used. When the sensor detects the reflected IR rays alarm will sound for 2 minutes.
