Abstract: “In this paper we present the details of a device we have developed which can automatically monitor the movements of people in a facility and control the lighting and air conditioning to minimize the wastage at the same time displaying the energy consumption details in any type of smart phone device. Not only it can display the status of the facility at a given time but also it can be operated manually to switch off some unwanted devices from anywhere in the world. It may be a device that a frequent traveler may like to have installed in his house since he can randomly on/off lighting in his house while he is away to mimic that there are people in the house. Some preliminary calculations shows that using this concept a typical house can save up to 30% of electricity whereby reducing the amount of carbon dioxide emitted to the environment. This percentage can be even more for a facility with many occupants with many unoccupied rooms. We are living in a world full of electronic appliances”
