Power saver for industrial and commercial establishment

Abstract

Power saver for industrial and commercial establishment can be used in places like where lighting is very important. The industries will be well illuminated with many lamps. When people are not present at a working place the lighting can be made OFF and when they are present, the lighting made ON. All these can be done through by IR sensor and LDR sensor. If a person entering to the monitored area, the IR sensors activates and sense the person, these sensation are given to the micro controller. The Infrared energy emitted from the living body is focused by a Fresnel lens segment. Then only the IR sensor activates. After sensing the person LDR checks the light intensity of the monitored area, whether it is bright or dark. Depending on the LDR output, the lamp may be ON / OFF. To display these working we are using LCD display. Our project helps in reducing the electricity bills.
