Electronic Eye Security Controlled System:-
Magic eye or electron eye is a one type of electronic device, used to watch continuously if any person is visiting your home . Nowadays, automation is a developing technology. For instance, a doorbell that continuously generates ringtones when an unauthorized person visit your home. This system gives security for homes when any unauthorized person is trying to enter into your home without your consent. This article gives an overview of electronic eye security control system project and its working.
Electronic Eye Security Control System Circuit Design:-
The circuit of the electronic eye security control system is separated into two parts such as logic circuit and power supply. The power supply circuit is designed with a battery, capacitors, P-N junction diode and regulators. Here diode is connected in forward bias mode and it protects the circuit from negative voltages.When the battery is connected in reverse polarity, there is a chance of circuit damage. So the diode is connected in the forward bias, that allows the flow of current in only one direction. The voltage across the diode is 0.7V.
A voltage regulator (IC 7805) is used to regulate the o/p voltage of the circuit. Here 05 denotes the o/p voltage and 78 denotes the series. Thus 5 volts is generated at the o/p of the voltage regulator. To eliminate the ripples two capacitors are connected before and after of the voltage regulator. Thus the voltage which is generated from the voltage regulator is applied to the logic circuit.
Description:-
The main concept of this project is to design an Electronic Eye Security Controlled System for homes and public places like banks, malls, etc. This project uses a LDR sensor to sense the intensity of light and produces an alarm for representing thefts, and also switches ON the lights.
This electronic security system is placed inside lockers and cash boxes in such a way that if an unauthorized person tries to open the locker door and uses a torch light to find the valuable things. The torch light falls on the electronic eye gives a signal to the buzzer.
This project can be designed to secure lockers and cash boxes where security is needed like homes, banks, etc. This project uses a 14-stage-ripple-binary counter to detect the intensity of light through the light dependent resistor. The relay driver is connected with the binary counter to control the different loads. The buzzer is attached to the circuit using a transistor to give an indication to the users.
Whenever an intensity of light falls on the LDR then the resistance of this LDR will decrease, and thus, the ripple counter triggers the transistors. Also, these transistors trigger the buzzer and load connected to the relay to indicate a theft.
Furthermore, this Electronic eye security control system project can be enhanced by using a microcontroller and a GSM modem. The GSM based home security system can be interfaced with the microcontroller to send & receive an SMS to the authorized person in case of robbery.
