Design and Construction of a Wireless Based Electrical Appliance Control System

The wireless based electrical appliance control system puts forth a system which enables users to control home appliances using mobile phone or computer with the aid of an application device, The design makes use of an efficient and low-cost technology for controlling the appliances thus minimizing the power wastage. The interface of the mobile application is used to send signals to another device connected to an 8052 microcontroller programmed to interpret the signal from the phone and control electrical loads via relays switched with transistors, the complete system operates on a 5 volts power supply which is obtained from the public mains. The design is built for the sole purpose of efficient control of electrical appliances, part of its objectives is to embed a user friendly control interface for electrical device using internet device, and it is a fast and efficient approach to control electrical appliances. The design is a viable one in the sense that it will go a long way in helping to checkmate unnecessary wastage of voltage and making it more convenient to control electrical appliances from even a remote area.
