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 of Study
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.
1.3 Scope of Study
The system can sense human touch and movement then triggers an alarm when powered with a 9v battery. It is a home intruder system that stops intruders before they get in and can summon help immediately making sure the family under its protection is absolutely safe.
1.4 Justification of the Study
This project makes it difficult for intruders to break into a home when there is a spotlight shining down to them. Then with the light dependent resistor that works with the spot of light, makes this project a home intruder system that keeps criminals further away from a family.
1.5 Constraint of the Study
The biggest setback experienced during the course of this project is financial difficulties in funding the design of the project Secondly, sourcing of materials and components used was not easy. Finding the motion sensor wasn't an easy task. Some of the components I used for this project were very difficult to find like the transistor for buffer. Furthermore, I received a severe electric shock while trying to interface some circuits into my design that made me to almost give up.
