Smart Lighting System Using PIR

Human beings are wasting too much of electrical energy by not turning off the lights, fans and many other electrical appliances when they are not using it. To overcome this problem we have developed a device that can be fitted anywhere in offices or homes. As the device will detect the presence of Human and automatically turn on and off the device. In this project, we are controlling light/bulb using PIR motion sensor. We are going to use the PIR motion sensor to detect the presence of a human body and then we will control the light/bulb according to the output of motion sensor. This can be used in small areas like bathrooms or store rooms. We can place the motion sensor at the door of a room and when someone will enter the room, the motion sensor will detect it and light will get on.
