ABSTRACT

In the present world of the human mind always need information of interest to control systems of his/her choice. In the age of electronic systems it is important to control and acquire information from everywhere. Although many methods to remotely control systems have been devised, the methods have the problems. Hence the need for special devices and software came to control the system. This suggests a method for control using the DTMF tone generated when the user pushes mobile phone keypad buttons or when connected to a remote mobile system. In wireless technology, everything is going to be in digital and wireless, and the cell phone is the key player in wireless technology today. Nowadays possessing of a mobile is considered as a basic commodity and the trends in wireless technology changing day-by-day. Today the working is going on how to develop remote devices without the presence of man and to reduce to the time factor and labor. Our project belongs to that race and by using it we can control any electronic devices through a touch cell phone, with one Call. Traditionally electrical appliances in a home are controlled via switches that regulate the electricity. As the world gets more and more technologically advanced, Home automation is becoming more and more popular around the world and is becoming a common practice. Home automation takes care of a lot of different activities in the house. In this project we propose a unique System for Home automation utilizing Dual Tone Multi Frequency (DTMF) that is paired with a wireless module to provide seamless wireless control over many devices in a house.

INTRODUCTION

In the present world of wireless technology everything is going to be digital and wireless, and the cell phone is the key player in wireless technology today. Today technology made the possessing of a mobile, considered as a basic commodity and the trends in wireless technology changing day-by-day and today the working is going on how to develop remote devices without the presence of man and to reduce to the time factor and labor, and our project belongs to that race and by using it we can control any electronic devices through a touch cell phone, with one Call. The aim of the proposed system is to develop a cost effective solution that will provide controlling of industrial appliances remotely and enable home security against intrusion in the absence of homeowner. The system provides availability due to development of a low cost system. The industrial appliances control system with an affordable cost was thought to...
