PIC based load controller

Abstract

Home automation is designed to prevent an actual confrontation between a returning occupant and an intruder. In the market, we found out many systems that can be use to protect the property. However if a member of the family was away, we wanted a system that would inform the member if the house has being broken into. This was ultimate safety that one looks for in a home security system. We can also add features such as lpg gas leakage, fire breakdowns or even water tank overflow. Chapter 2 deals with the history of home automation along a brief description of Hardware & Software. Chapter 3 deals with the basics of GSM System. It gives the details of the adopted methodology which includes Block diagram, Circuit diagram, Hardware & Software used. Chapter 4 deals with Analysis, Experimentation & Results. It includes descriptions of various ICs used, PCB layout & Challenges faced during our project. Chapter 5 deals with the future scope and conclusion. In order to make the system ‘smart’, we have made the mobile phone almost a universal remote controller, where in the user can control various devices at his home just through the SMS. We have even solved the i/o port limitations by expanding the ports using latches and buffers so that more sensors can be interfaced in future.
