Abstract
Most of the appliances in the house and office including light and fan are operated manually, leading to wasted electricity. And if there is no use, they are left on. In this paper, we propose a solution for the convenient and cost-efficient prevention of waste of electricity. This system includes two Infrared object detection sensor at the entrance of each room to determine the direction of people and their number in the room, one PIR sensor in the ceiling of each room to sense the movement, and one pressure sensor under an office chair or bed to sense a person’s pressure. It is proposed that such an intelligent power-saving device saves power and expands the user console level with the lowest cost. where has been proven the costs of this smart system Much less than wasted power costs within ten hours at least. This system is used to reduce power consumption it is possible to reach high effectiveness in energy management.
In this thesis, we introduced a smart automated controlling system for controlling the lighting of home appliances. This saves huge amounts of energy. This thesis provided a solution for preventing the waste of home electrical energy in a comfortable and cost-effective way. Our system utilizes the use of Infrared Object Detection Sensors and Motion Sensors. Depending on the person’s presence, devices such as lamps, fans, etc. are switched on or off. An example of an apartment is given for the system application. Also, calculations for a whole building composed of 10 apartments are given. The cost is calculated and the investment impact, in the long run, is discussed. This system can be extended and applied to a whole city or district.
