In this Thesis, we have studied, designed and implemented an energy and economic efficient smart plug system and achieves high rates of performance. At the beginning, a comprehensive reference studying the Smart Plug devices. The Smart Plug device was studied, designed and implemented using, which Turn-Off electrical loads in Standby mode to minimize power consumption. The status of all devices connected to the smart plug is shown on the computer display using smart monitor application. The design and implementation of Smart Plug system has saved 1.3% of the total energy consumed in the home per month while achieving economic feasibility and improving the cost of the economic return of the total consumers about 0.7% through the use of the smart plug that has been implemented.
