Wireless smart power saving system for home automation

Mostly in home and office appliances like light and fan are manually controlled which leads to power wastage. They are left ON even if there is no usage and even when the appliances are in use their operation is not controlled by environmental conditions like daylight and temperature variation. By making a smart automated controlling system for appliances we can save the power by huge amount. In this paper we are providing a solution for preventing the wastage of power in a comfortable and cost effective way. Our system consists of an electronic door lock and power saving module. When the person enters the correct password in door lock the power saving module is switched on. The power saving module switches the appliances in the room based on the presence of the person. It also controls the power delivered to fan and light according to temperature of room and natural daylight intensity.
