1. INTRODUCTION We use many different types of communication in control applications to control home appliances, industrial appliances, and other type of automation. There are two types of communication that is we generally use - one is wired and other one is wireless. In wireless communication we transmit signal wirelessly, like using radio frequency (RF) and in wired communication in which we use wires like copper wire. In this project “DTMF Based Home Automation System” we are going to control our home appliances wirelessly. Other important feature of this project is, that we are not going to use any microcontroller in it. . The remote control used in home automation systems, is a wonderful feature that everyone would like to enjoy, if they were not expensive to install, maintain, and able to be use from long distance. With such automation one can switch ON and OFF lights, Ac etc. from a remote distance. In our project we have tried to implement this home automation technique u
