Abstract:
Newly, smart card technology are bring used in a number of around the world, on
the other hand security has become significant in information technology. But there
are few sectors in our country where security system has been adopted. Security
system is more acceptable to the technologically unskilled people. Security system
is the main concern of this project. The purpose of this project is to become
familiar with the implementation of developing a security system. We used smart
card with LDR using optoelectronic for security purpose and the alert will be
displayed by LED and buzzer alarm. The objective of this project is to design a
simple, easy to electronic circuit. It communicates with the LDR in real-time in
order to control the light and buzzer alarm according to the necessary condition.
