future scope of electronic eye controlled security system


Abstract

Electronic eye is also called magic eye. As the automation is emerging technology these days, just imagine a door bell that automatically rings when a person visit your home. This also provides security when any person is trying to enter into your home without your permission. Electronic eye is the electronic device that continuously watches if anyone is visiting your home. This article presents the circuit of electronic eye. Before going to know complete details about this circuit, get an idea about Light Activated Switch Circuit using LDR.

Introduction

The project is designed as a security system based on photo 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 for necessary action. This concept is very useful to deter burglars from banks, malls, jewellery stores and also in homes.

The system is based on an electronic eye: it is an LDR sensor, called light dependant resistor. When light falls on the sensor, its resistance drastically decreases which lead to triggering an alarm to alert the user.This system best suits in the application of providing friendly security system for cash boxes and lockers, which can be found in malls, jeweler shops, and banks.

The circuit is placed inside the cash box or locker in such a way that, when the burglar opens the locker and uses a torch light to find the valuables, the light falls on the circuit which contains an electronic eye (LDR) and gives a signal to the ripple counter. This activates the alarm, and indicates a burglary attempt. Also a lamp is used to indicate the theft when the light falls on the LDR.

Further the project can be enhanced by using a GSM modem and a microcontroller. Gsm modem can be interfaced to the microcontroller to send an SMS to the user in case of burglary.
