The document describes a project report for a GSM-based home security system. The system uses an 8051 microcontroller, sensors for fire, burglary and gas, a GSM module, and other components to automate security and monitoring of a home. When intrusions or issues are detected, the system will send alerts to users via the GSM network. The report provides details on the components used, how the system was integrated and programmed, its advantages, and potential applications. It aims to develop a low-cost security solution that provides continuous monitoring through a multi-layered approach.

ABSTRACT The final year project aims at exposing the students undergoing higher technical studies to the thoughts and logic that must be developed to ensure that one is able to integrate his/her ideas into something concrete. This generally is initiated by the inception of an idea or a concept, which not only aims at developing a product (Hardware or Software), but also the in-depth study of the earlier existing products in the same category and their deficiencies. Accordingly an approach is taken to propose a solution, which is better from the previous ones in one respect or the other. With the same approach in mind, we, the final year students of Bachelor of Technology (Electronics and Telecommunication), have taken up the ADVANCE GSM BASED HOME SECURITY SYSTEM as our final year project. Automated security systems are a useful addition to today’s home where safety is an important issue. Vision-based security systems have the advantage of being easy to set up, inexpensive and non-obtrusive. Home security system for detecting an intrusion into a monitored area by an infrared detector. A security system has a flee-standing intrusion detector. The free standing intrusion detector has a transmitter coupled with a portable receiver to alert a homeowner that an intrusion has taken place or occurred within a pre-set time period. 3
- 4. ACKNOWLEGDEMENTS It is our proud privilege to have Mr. Pardeep Kumar as our mentor for this project, GSM based home security system. He has been an immense help to us since the beginning of the project. He guided us at tough times and helped us achieve this goal. We are very thankful to him for his help and support. We would also like to extend our thanks to our H.O.D, Col. R.K. Kapur for his undying faith in us and making us believe in ourselves. His guidance has been the reason we could complete this project. 4

- 8. 1. INTRODUCTION In today’s age of digital technology and intelligent systems, home automation has become one of the fastest developing application-based technologies in the world. The idea of comfortable living in home has since changed for the past decade as digital, vision and wireless technologies are integrated into it. Intelligent homes, in simple terms, can be described as homes that are fully automated in terms of carrying out a predetermined task, providing feedback to the users, and responding accordingly to situations. In other words, it simply allows many aspects of the home system such as temperature and lighting control, network and communications, entertainment system, emergency response and security monitoring systems to be automated and controlled, both near and at a distance. Automated security systems play an important role of providing an extra layer of security through user authentication to prevent break-ins at entry points and also to track illegal intrusions or unsolicited activities within the vicinity of the home (indoors and outdoors). There has been much research done in the design of various types of automated security systems. Sensor-based systems that rely on contact or movement sensors or contact-based systems such as fingerprint and palm print scan or keypad activation that require substantial amount of contact with an input device. Many security systems are based on only a single system. In an event of system failure or intrusion of the user authentication, there is no backup system to monitor the home continually. This shortcoming can be dealt with using multiple security systems (or multi-layered security systems). However, multi-system implementations will definitely be more demanding in terms of computational cost and organization. 8
