The Motion & Bluetooth Controlled Office Automation Cum Power Saver, where the lights in the room will automatically turn on upon detecting a human motion and stay turned on until the person has left the room or there is no motion. Initially, when there is no human movement, the PIR Sensor does not detect any person and its OUT pin stays LOW. When the person enters the room, the change in infrared radiation in the room is detected by the PIR Sensor. The output of the PIR Sensor becomes HIGH. Since the Data OUT of the Sensor is connected to Digital Pin 8 of Arduino, whenever it becomes HIGH, Arduino will activate the relay by making the relay pin LOW as the relay module is an active LOW module. This will turn the Light ON. The light stays turned ON as long as there is movement in front of the sensor. If the person takes a nap or leaves the room, the IR Radiation will become stable (there will be no change) and hence, the Data OUT of the PIR Sensor will become LOW. This, in turn, will make the Arduino turn OFF the relay (make the relay pin HIGH) and the room light will be turned OFF. Along with Motion controlled this system will have control in users hand on Android mobile; the user can turn ON/OFF Load in a single click. The Android application will help the user to monitor the current status of Motion Sensor as well as to update new Delay Time to keep the load on even there is no Motion. By using the Android application it will be possible for the user to say after what time the system will shut down the load. The system will start buzzing if time to Shut Down the load is less than 30 Sec.
