MOTIVATION FOR CHOOSIN G THEPROJECT

A global wireless network deploy across businessenterprise location. The work of the administrator is to find a

wired or wireless security device to prevent the theft attacks andthreats. So monitoring and to identify the security alert and

configuring it is a time taking process for a larger organization.

There are many home based security devices forsurveillance process, but they are either wired or expensive inuse. Where as my project deals with a security system with latest

wireless technology with less expensive in cost when comparedto other security devices. Here I am using all the basiccomponents that are used in daily life like mobile phones, SIMcard, GSM modem etc, so this makes my project cheaper and

very simple to use.

AIM OF THE PROJECTThe Need for security to the house when we are in and moving along to the office will be great constraints for us. The communication hasbrought a way to secure the properties of our home. GSM BASEDHOUSE MAINTANENCE AND SECURITY SYSTEM FOR LEGLESS PEOPLE is a boon for legless people to easily control and

monitor their houses from the place where they are right now by using their ordinary mobile phones. It serves two main objectives that ishouse maintenance and also offer increased security system.

The first objective House maintenance is achieved by using microcontroller and relay circuit. The authorized person gives theacknowledgement to that device, then the microcontroller will switchon or off the electrical appliances and send the state of that appliances

whether they are currently working or not. The authorized person candone this by using their normal mobile phones.

The second objective of our paper is to offer increased house security that is when there is any intrusion or unauthorized entry the alert message issend to owner. Who can close the door and enable the security alarm

system by sending a coded message to prevent from any actions of intruders. The whole project is based upon the hardware design withsoftware development using embedded system.

This project design makes use of 8051 microcontroller for interfacing to

various hardware interfaces.

Technology today is seeing its heights in all the areas, especially in thearea of embedded system.

It is true that every electronic gadget that is used in daily life right from a pc keyboard to a refrigerator is an embedded system.

This itself shows how vastly the technology is expanding. As thetechnology is improving day to day many thing of our daily life became so

simple and easy.

FUTURE SCOPE

The modern mobile technology using the G SM featureis offering inspiring appearance and capability that once were not being able in use 15 years ago. So by making use of these technology further developments in the security aspects can be made there by reducing the cost of theproduct, increasing the accuracy and working of theproduct. Since the mobile phones are being used by

millions of people worldwide, this project can beimplemented by each and every individual in near future.

FUTURE ENHANCEMENTThe future scope of my project is highly rated because of its simplicity in working and economic in cost for settingup the device.

In order to avoid the burglar activities when we go outby locking our home this will be necessary and itsactivation process is also quite simple, just we need toenable the sensor and we will receive an SMS if any unauthorized person enters the sensor zone and we cantake the necessary steps.

Hence according to my view in near future each homeshould have this security device installed.

CONCLUSIONI have established very clearly about the G SM Security system using SMS. W e can say that this is a birth for a newbrand era . G SM Security system using SMS can be appliedfor your security with convenience. G SM Security system

has been taken into a new dimension.

This document presents a mobile controlled and user-friendly approach to the available home security. It is real-time monitor-able and remote controllable. This systemcan easily be implemented because of its no necessity to wiring between the appliances since it uses wirelesscommunication standards. Another enhancement of thesystem is its high security.
