It is very important that now a day’s reduction of power consumption and optimal utilization of the power sources which is available for consumer. In this paper we have designed a controlling of electrical appliance through matrix-based system. The PIR sensor is placed in the coordination of column and row for the particular interval. The PIR sensor automatically controls the electrical appliance based on the object detection. The system is equipped with temperature sensor to control the operational of the fans seasonally without the intervention of manual switches. Additional features are introduced in the control using controller for making it a smart system. The system based on simplex wireless communication in which the sensors are connected to a RF transmitter which transmits the data to the RF receiver at the controller side and the appliances are controlled according the data send by the transmitter. The manual switches are taken down by the electromagnetic relay switches for the controlling of the lights and fans which are distributed across the room in a matrix form.
