Abstract

This project is to design a circuit that will allow us to remotely control home or office appliance through a telephone. This project is developed to complete our daily needs where we can activate or switch on domestic appliances from a great distance using only telephone or cellular phone. This project involves decoding of telephone signal and channeling it to the relevant appliances through a Demultiplexer. The Demultiplexer is connected to the relays that operate the relevant appliance. The appliances must be full time connected to the power supply in order to function immediately and automatically when the project circuit operates once received command to switch on the appliances. This project circuit is to be connected in parallel to the telephone instrument to allow the telephone can be used to switch on or switch off the appliance and also can used for normal conversation.
