Design and Implementation of a Smart Security System Using GSM Technologies Via Short Message Service(SMS) and Calling Function
Abstract
This paper proposes the development of a GSM – based smart security system. It is a combination of electronic devices /equipment working together to detect a fire and any human moment. GSM SIM-300, Microcontroller, Sensors have been used to realize this system. This is a cost effective system that detects fire or smoke or human presence and sends alert information to a registered mobile phone for quick and immediate action thereby, avoiding unnecessary and costly industrial and domestic breakdown. A Short Message Service (SMS) and a Calling function is used as a method of wireless connection in the designed system.

Introduction
What is a security system? Security is the degree of protection against damages, danger, loss and crime. A security system provides a form of protection that ensures the safety and security of the assets and the threat but is not limited to the elimination of either the asset or the threat. Now a day's wireless technology is used instead of wired topological connection. GSM (Global System for Mobile Communication) technology makes used to communicate input signal from appliances to output message on device. That means after detection of any intrusion GSM Modem sends the appropriate message to registered phone. The signals or data which is comes from sensors or other equipment digitize it by GSM module and send it to receiver. The wireless communication is increasing day by day [2]. This has motivated us to use mobile phones to identify the problem and to receive a feedback SMS about the security and safety. The system operates with the help of sensors installed in this system.
Existing systems
1. Wired System,
2. RF Based Security System,
3. Web enabled Security System.
Disadvantage of Existing Systems
1. Difficult to maintain
2. Need internet access
3. Distance.
Proposed System
The proposed system uses GSM module which enables us to know the security status when we are away.
Conclusion
In this project, a low cost, user-friendly, simple, secure and universally acceptable solution for security has been introduced. This approach has achieved the target to control the device remotely using an GSM-based system satisfying user needs and requirements. The system is cost-effective as compared to the previously existing systems in the market and can be easily implemented with high reliability and security. The basic level of security control and remote monitoring has been implemented. The system is extendible and more levels can be further developed. Hence, we can conclude that the required goals and objectives have been achieved.
