The Complete project is about The motion activated sensor circuit and its working. But here is one interesting fact: the entire circuit including the PIR Motion sensor is working in Direct AC voltage. Here we are not using 12V DC…
The Motion sensor circuit is working based on a 555 timer IC. The entire article contains PCB layout of Motion sensor automatically activating light PCB. The circuit can handle the 220v AC supply. 220v AC Motion Sensor project PCB Layout…
Motion sensor circuit 220v This is a very simple and low cost 220v AC motion sensor light circuit. This design using A PIR sensor and Transformerless power supply and a triac based control system. The power supply section completely working…
PIR Motion sensor The PIR motion sensor. PIR is known as the passive infrared. PIR sensors enable you to sense motion, nearly always used to observe whether or not an individual’s has moved in or out of the sensors range.…
