GSM Based Home Security System


GSM Based Home Security System 

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
