DESIGN AND IMPLEMENTATION OF GSM BASED REMOTE SWITCHING SYSTEM

CHAPTER ONE

INTRODUCTION

1.1 Background of study

Has technology transformed humankind into omniscient being? Years back, communication was done through difficult means like travelling to the destination of the second party, posting letters est. Today people can communicate easily through various means like e-mailing, face booking, GSM etc. The new age of technology has redefined communication, most people nowadays have access to mobile phones and thus the world indeed has become a global village. At any given moment, any particular individual can be contacted with the mobile phone. But application of mobile phones cannot be restricted to sending SMS or starting conversation. New innovation and ideas can be generated from it that can further enhance its capabilities. Technologies such as infra-red, Bluetooth etc which has developed in recent years goes to show the very fact that improvement are infact possible and those improvement have eased our life and the way we live. Remote management of several home and offices appliances is a subject of growing interest and in recent years we have seen many systems providing such controls

1.2 Statement of problem

Technology has advanced so much in the last decade or two that it has made life more efficient and comfortable. The comfort of being able to take control of devices from one particular location has become imperative (i.e. important) as it saves a lot of time and effort. Therefore there arises a need to do so in a systematic manner which will be implemented in the proposed system.

1.3 Project Aims and objectives

The project "GSM control system" as the title suggests is aimed to construct a control system that enables the complete control of the interface on which it is based.

General objectives of the project are :

a. To co-ordinate appliances and other devices through calls.

b. To effectively receive and transmit data via calls.

c. To eliminate the need of being physically present in any location for tasks involving the operation of appliances with household/office.

d. Minimize power and time wastage.

1.4 Justification of study

o The proposed project can be used as a reference or as a base of realizing a scheme to be implemented in other project of greater level such as device synchronization, temperature updates, weather forecasting etc.

o The project itself can be modified to achieve a complete home automation system which will then create a platform for the user to interface between himself and the household.
