The electronic eye controlled security system is invented in the year 1997, base of operations in New Delhi. There are some organizations under the security systems are electronic eye Pvt. Ltd, Indian institute of science & technology, electronic eye systems, and Mahamahi Exims. This system creates a whole collection of high-tech security and surveillance products. These 0Systems work on the combination of system and project execution at the customers place for numerous surveillance products. This article discusses what is an electronic eye and electronic eye controlled security system project with a brief explanation.
What is an Electronic Eye?
The term electron eye is also called as magic eye, is a one type of electronic device, used for lookout always if any person is visiting your home. Nowadays, automation is an emerging technology. For example, a doorbell generates continuous ringtones when an unauthorized person visits your home. This system gives safety for homes when any illegal person is trying to enter into your home without your permission.
Electronic Eye Controlled Security System
Here is a smart security system for your cash box that stops the theft attempt by activating an emergency beeper. A battery is provided to supply the power to the circuit with the help of a switch. When cash box is closed LDR in dark state resets the IC CD4060 which goes low and has no impact on BC547 results Relay in off condition. When LDR in bright mode, the counter will start counting and oscillates resulting both transistors in ON condition indicating load ON and buzzer will blow. This circuit is mainly useful at Banks,Hotels,shopping malls, household appliances..etc
The electronic eye controlled security system is built with a battery, IC 4060 binary counter/divider, LDR, BC548–NPN transistor, relay, buzzer, push buttons, resistors,capacitors and LED.
- An electrical battery is a combination of one or more electrochemical cells, used to convert stored chemical energy into electrical energy.
- The battery has become a common power source for many household, robotics and industrial applications.
- Larger batteries provide standby power for telephone exchanges or computer data centers.
CD4060 (Ripple Binary Counter/Divider)
- CD4060 consists of an oscillator section and 14 ripple carry binary counter stages.
- The oscillator configuration allows design of either RC or crystal oscillator circuits.
- A RESET input is provided which resets the counter to the all O’s state and disables the oscillator.
- All counter stages are master slave flip-flops. All inputs and outputs are fully buffered.
- Schmitt trigger action on the input pulse line permits unlimited input pulse rise and fall times.
- High Voltage Type (20V Rating)
- Common Reset
- 12MHz Clock Rate at 15V
- Fully Static Operation
- Buffered Inputs and Outputs
- Schmitt Trigger Input Pulse Line
- Standardized, Symmetrical Output Characteristics
- 100% Tested for Quiescent Current at 20V
- 5V, 10V and 15V Parametric Ratings
LDR (Light Dependent Resistor)
- A light dependent resistor (LDR) is a resistor whose resistance drops with increasing incident light intensity.
- It can also be stated to as photoconductor.
- If light falling on the device, the photons absorbed by the semiconductor give bound electrons enough energy to jump into the conduction band.
- The resulting free electron (and its hole partner) conducts electricity, thereby lowering resistance.
- A photoelectric device can be either intrinsic or extrinsic. An intrinsic semiconductor has its own charge carriers and is not an efficient semiconductor, e.g. silicon.
- Extrinsic devices have impurities, also called dopants, added whose ground state energy is closer to the conduction band; since the electrons do not have as far to jump, lower energy photons (i.e., longer wavelengths and lower frequencies) are sufficient to trigger the device.
- Example of extrinsic devices is phosphorous atoms.
- The BC548 transistor is an NPN Epitaxial Silicon Transistor.
- The BC548 transistor is a general-purpose transistor in small plastic packages.
- It is used in general-purpose switching and amplification BC848/BC548 series 45 V, 100 mA NPN general-purpose transistors.
- Whenever base is high, then current starts flowing through base and emitter and after that only current will pass from collector to emitter.
- It is a electromagnetic switch
- Used to control the electrical devices
- Copper core, magnetic flux plays main role here
- The relay switches connections are usually labeled COM, NC and NO:
- COM = Common, always connect to this; it is the moving part of the itch.
- NC = Normally Closed, COM is connected to this when the relay coil is off.
- NO = Normally Open, COM is connected to this when the relay coil is on
This buzzer is a piece type audio signaling device, which has a piece element and a oscillating circuit inside which oscillates the piezo brass base plate, which when given voltage difference produces the sound of a predefined frequency.
- These high reliability piezo buzzers are applicable to general electronics equipment.
- Compact, pin terminal type Piezo buzzer with 4 KHz output.
- Pin type terminal construction enables direct mounting onto printed circuit boards.
Working of Project
The main concept of this project is to design an Electronic Eye Security Controlled System for where the security is needed like homes, malls, banks, etc. The proposed system uses a light dependent resistor to detect the light intensity and generates an alarm sound for thefts, and also turns ON the lights.
This system is placed inside lockers and cash boxes in such a way that if a person or theft tries to open the door lock and uses a torch light to treasure the valuable things. The light falls on the electronic eye and immediately gives a command to the buzzer.
This project can be designed to secure lockers and cash boxes where security is needed like homes, banks, etc. This system uses a 14-stage-ripple-binary counter to detect the light intensity through the LDR (light dependent resistor). The relay driver is attached to the binary counter to switch various loads. The buzzer is connected to the circuit with the help of a transistor to give a sign to the users.
When an intensity of light drops on the LDR then the LDR resistance will drop, and thus, the ripple counter activates the transistors to make the buzzer ON and load connected to the relay to specify a theft.
In the future, this Electronic eye security control system project can be improved by using a GSM modem and microcontroller. The home security system using GSM can be interfaced with the microcontroller to send and receive an SMS to the owner in case of theft.
Thus, this is all bout LDR based electronic eye controlled security system. The applications of this system mainly include garage door opening circuits, door bell circuits, and various security applications. We hope hat you’ve got a better understanding of this project.
