PORTABLE SECURITY SYSTEM

A security system is a system used to prevent from and protect against assault,
damage, fire, fraud, invasion of privacy, theft, unlawful entry, and other such
occurrences caused by deliberate action. A portable security system is designed to
be small, easy to carry or move and it is normally being powered by a battery. The
operation of a security system is to detect, to delay, and to alarm. Normally, alarm
systems use several sensor systems. This project is about designing and
developing a Portable Security System that helps to detect a door knob touch, to
sense an opening door and to sense a movement in a room. A portable security
system can be an option for those who rent apartments and not having the
permission of the landlord to begin drilling to install security systems. The system
is used to ensure safety and confidential usage of a room too. The significant part
of the system is the portability because we make use of a transmitter and receiver,
so that an appropriate security breach messages can still be communicated from
the door to the person inside the room. The initial stage of the project involves
research and feasibility studies of a security system. The system design requires
the selection of hardware, including sensors, the transmitter and receiver and a
microcontroller. The security system prototype is built part by part. And then, the
input and output components of the microcontroller is interfaced with the
transmitter and receiver module. The system should trigger the alarm and user will
require to key in a special code to stop the alarm.
