This AUTOMATIC ROOM LIGHT CONTROLLER WITH VISITOR COUNTER USING IR SENSOR project is designed and developed to control the ac power on/off with automatic room light using IR sensor.
The light control depends on weather one person is in the room or not. Using ir sensor (tsop1738) we can find the person entered into the room or the person exit from the room; the no. of persons entered into the room counts by the micro controller and displays on the LCD. If any person entered, the ir sensor interrupts the micro controller then micro controller turn on/off the ac bulb by checking the count. In the absence of person in the room, the light automatically goes to the off position. For fast switching, we use triac ac control circuit resulting the power can save automatically.
