CHAPTER ONE
INTRODUCTION
1.1   Background of Study
Environmental, home and office security against intruders has become a thing of individual, national and international concern. The essence of this project is to provide a cost effective and more efficient security system in areas like homes, industries military etc. The application of this project will enhance effectiveness necessitating to security measures. It relevance, upgrades the conventional security system to automated system that will require little of human intervention. This project also builds a platform for further sophistication of automated security system by detailing all the measures taken in realizing this system. This will ensure a complete intruder proof system which will take care.
Intruder for home and office use is a design that detects the presence of an intruder in restricted areas and also informs the user by triggering an alarm. The system is based on hardware controller and other electronic design. This hardware controller uses two sensors, one for human touch sensing and the other for movement. The movement sensor uses light dependent resistor which must work in hand with a security light incident to it. With the security light, the system can receive signal when the intruder is around and translate the received signal from the sensors to useful information. In this design we have implored the use of hardware components, creativity and logics to bring about the entire project.
1.2    Aims and Objective
The aim and objective of this project is to provide a cost effective and efficient security device for home and office use, to offer its users a paramount security.
