Abstract
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 equipments 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.
