ELECTRONIC EYE CONTROLLED SECURITY SYSTEM ABSTRACT
The project is designed designed as a security system system based on photo sensing sensing arrangement. It uses a 14- stage ripple carry binary counter to sense the light intensity through LDR. The output drives a buzzer and a relay or necessary action. This concept is very useul to deter burglars rom ban!s" malls" je#ellery stores and also in homes. The system is based on an electronic eye$ it is an LDR sensor" called light dependant resist resistor. or. %hen %hen light light alls alls on the sensor sensor"" its its resist resistanc ancee drasti drastical cally ly decrea decreases ses #hich #hich lead lead to triggering an alarm to alert the user. This system best suits in the application o providing security or cash bo&es and loc!ers" #hich can be ound in malls" je#eler shops" and ban!s. The circuit is placed inside the cash bo& or loc!er in such a #ay that" #hen the burglar opens the loc!er and uses a torch light to ind the valuables" the light alls on the circuit #hich contains an electronic eye 'LDR( and gives a signal to the ripple counter. This activates the alarm" and indicates a burglary attempt. )lso a lamp is used to indicate the thet #hen the light alls on the LDR. *urther the project can be enhanced by using a +, modem and a microcontroller. +sm modem can be interaced to the microcontroller to send an ,, to the user in case o burglary.
%hat is electronic eye It is a secured monitoring system 2o# does it unction It unctions by sensing light in a closed chamber %here can I use it 3ou can use it #ith precious items li!e cash bo&" je#el bo&" loc!ers etc.
