The world electrical energy consumption statistics shows that consumption of electricity is growing gradually each year, and more over the rates are also increasing, because of increasing in prices of natural gas and oil, which are the major raw materials for production of electricity. Since raw materials are not infinite, world is looking for alternative source of energy, and while researches are being done in order to bring consumption of electricity to minimum level in Universiti Teknologi Petronas residential villages new combination of sensors based system needed to be applied. The purpose of this project is to show the efficiency of a new system, which is going to save more electrical energy. Motion and light sensors are main devices which are going to be involved in this project. A standard 40 watt fluorescent lamp consumes electricity per month is around 10 ringgits when it is turned on. Here in UTP there are several blocks in each village. Let’s say 50% of one block left lights of corridor and lights in stairs turned on during day time, which will mean for those 50% of lighting electricity will be wasted. Using motion and light sensor based switches for lighting in places such as corridors, stairs and rest rooms the electrical energy will be used just as much as it’s needed. This means normal switches are going to be fully automated, so that there will be no need to switch lights on and off manually, as a result the system will be consuming only when it is dark and when motion is detected, which means the system will not be operating during day time in respective areas.
