GSM Based Home Security System Synopsis/ Abstract

GSM Based Home Security System

Abstract

Home security has been a major issue where crime is increasing and everybody wants to take proper measures to prevent intrusion. In addition there was a need to automate home so that user can take advantage of the technological advancement in such a way that a person getting off the office does not get melted with the hot climate.

Introduction

The project is aimed at developing the security of Home against Intruders , Gas Leak and Fire . In any of the above three cases any one met while you are out of your home than the device sends SMS to the emergency no provided to it.

The report consists of a background into the area of 8051 microcontroller and mobile communication, how they are interfaced to each other and AT (Attention) commands set used in communication.

HARDWARE USED

1. AT command supporting GSM mobile phone.

2. 89S52 Microcontroller

3. Max 232 IC.

4. Relays

5. Relay driver IC ULN 2803

6. Voltage regulator 7805.

7. Diode IN4007

8. GSM Phone

9. LPG Gas Sensor

SOFTWARE USED

1. Keil u-Vision 3.0

Keil Software is used provide you with software development tools for 8051 based microcontrollers. With the Keil tools, you can generate embedded applications for virtually every 8051 derivative. The supported microcontrollers are listed in the µ-vision

2. PRO51 Programmer Software

WIRELESS MESSAGING VIA MOBILE/LANDLINE

Project Descreption

The main objective of this system is to transmit message or text through ordinary Land Line Telephone/mobile from one end (source) to another end (designation). This is get achieved by the DTMF technology. It has two sections one for editing the text and to transmit the edited text and the other section consist for receiving the text message. The system works on the DTMF technology. (Dual Tone Multiple Frequency).
It involves several steps. They are
DTMF decoding/Encoding process
Ring sensing
ON/OFF hook detection
Displaying the message in LCD
The above process is get achieved by the microcontroller AT89S8252/AT89C51/52.Thus Microcontroller controls the whole system.
As the title “wireless messaging via mobile/landline phone” itself indicates that this project deals with the transfer of message from one mobile to another or one landline to another without using wire connection.

The DTMF tones sensing circuit display the message at LCD as sent by other end by means of tone transmission.

Applications:

DEFENCE, FUN & ENTERTAINMENT, GAMES & SPORTS, SURVILLANCE
