One of the major problems in the most populated and developing countries like India, is Energy or Power crisis. Hence, there is a pressing need to conserve power. There are many simple ways to save electricity, like using the electric and electronic gadgets whenever and wherever needed and switching them off, while not in use. But in places such as large auditoriums and meeting halls, there will be a fan or an Air-conditioner keeps running in unmanned area too, even before the people arrive. This contributes to a considerable amount of electricity wastage. There are many ways to prevent this wastage, like, installing IR sensors to detect people etc. These methods are quite costlier and complex for larger areas. Hence, here we propose a new method of controlling the power supply of auditoriums using, Image Processing. Here first we take a reference image of an empty auditorium and any change in that reference image is detected and then according to that change respective equipment's alone are turned on. Thus power wastage is controlled. This is dual usage system in which a camera is used for detecting people as well as surveillance purposes. This is very simple, efficient and cheaper technique to save energy. Another big advantage is, we can extend this up to applications like home automation etc.
