thanks in advance :-)

Hi,
The major components in this project is a GSM modem that enables SMS sending. This is a good guide to sending SMS from PC with source code in c++:

INTRODUCTION

Security is of prime importance in day-to-day life.
Security is the protection of something valuable to ensure that it is not stolen, lost, or altered.
This Project focuses on to implement GSM ( Global System for Mobile Communication) based Security System.
This system is implemented using an embedded microcontroller AT89S52.
If a GSM based security system is installed and any of the sensors is activated then GSM modem will send message to the required number.

Working principle
This project uses a GSM modem with micro controller

The microcontroller & the GSM modem are connected. And also some sensors like the light sensor, door sensor, touch sensor, emergency switch etc are wired to the microcontroller

In the receiver side receiver will demodulate the RF signals and check which sensor had gone out and will send messages to the corresponding number using GSM MODEM.

This device will be wired in banks to some sensors like door sensor, window sensor, movement detector,

Whenever any sensors send an output, the device (GSM mobile) will check it with its database and then send the SMS or it makes a call to the required person.

GSM MODULE
GSM has been the backbone of the phenomenal success in mobile telecom over the last decade. Now, at the dawn of the era of true broadband services, GSM continues to evolve to meet new demands.
GSM is an open, non-proprietary system that is constantly evolving. One of its great strengths is the international roaming capability.
This gives consumers seamless and same standardized same number contactability in more than 212 countries

GSM SPECIFICATION
Device Name : Wavecom
ROM (Flash) : 16Mb
RAM : 2Mb
Operating Voltage : 3.1 – 4.5 V
Receiving Frequency : 925 – 960 MHz
Transmitting Frequency : 880 – 915 MHz
