Electronic Eye Controlled Security System Introduction The main aim of this project is used to provide security system for cash boxes, lockers in malls, jeweler shops, homes and banks and also 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. http://www.edgefxkits.com/

Electronic Eye Controlled Security System Resistor Resistor is a passive two - terminal electrical component that implements electrical resistance as a circuit element. The ratio of the voltage applied across a resistor's terminals to the intensity of current through the circuit is called RESISTANCE. The relation is represented by Ohm's Law : V=IR http://www.edgefxkits.com/

Electronic Eye Controlled Security System IC- CD4060 IC- CD4060 is a ripple binary counter/divider. It 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. http://www.edgefxkits.com/

Electronic Eye Controlled Security System IC- CD4060 Features High Voltage Type (20V) 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 http://www.edgefxkits.com/

Electronic Eye Controlled Security System Description About Project This project is to design an Electronic Eye Security Controlled System for homes and public places like banks, malls, etc. It 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. When 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 giving a signal to the buzzer. http://www.edgefxkits.com/

Electronic Eye Controlled Security System Description About Project It uses a 14 stage ripple binary counter to detect the intensity of light through the light dependent resistor(LDR). 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. http://www.edgefxkits.com/

Electronic Eye Controlled Security System Description About Project Whenever an intensity of light falls on the LDR then the resistance of this LDR will decrease. Thus, the ripple counter triggers the transistors. Also, these transistors trigger the buzzer and load connected to the relay to indicate a theft. http://www.edgefxkits.com/

Electronic Eye Controlled Security System Working LDR senses the light intensity and generates an alarm for indicating thefts and also turns ON the light. If the cash box is in closed condition, the interior will be dark. Hence in the dark, LDR resets CD4060 and it stops oscillating and counting. So neither the buzzer sounds, nor the relay energizes, indicating that the cash box is closed. http://www.edgefxkits.com/

Electronic Eye Controlled Security System Working If someone tries to open the door of the cash box and uses a torch light to find the valuables. Then the light most probably from the burglar's touch falls on LDR fitted into the cash box. As a result, LDR conducts and goes low. Hence pin 14 of IC1 goes high for two seconds after the door is opened and goes low for another 2 seconds. http://www.edgefxkits.com/

Electronic Eye Controlled Security System Working So the buzzer sounds for two seconds and then falls silent for the following two seconds. This cycle repeats until the cash box is closed. http://www.edgefxkits.com/

Electronic Eye Controlled Security System Circuit Operation Initially, connect the circuit as shown in the circuit diagram on the bread board. http://www.edgefxkits.com/

Electronic Eye Controlled Security System Circuit Operation Now connect the supply voltage of 9v using battery. Place the LDR in light. You can observe no sound is produced from the buzzer. Place the LDR in dark, buzzer starts ringing. LED connected to the buzzer also starts blinking. As the intensity falling on the LDR increases, sound produced by the buzzer increases. http://www.edgefxkits.com/

Electronic Eye Controlled Security System Applications Mainly used in security applications. Door bell circuits. Garage door opening circuits. http://www.edgefxkits.com/

Electronic Eye Controlled Security System Advantages Used to provide Security. http://www.edgefxkits.com/

Electronic Eye Controlled Security System Disadvantages Light is required in front of door bell. If any person come in & out then the bell will ring. http://www.edgefxkits.com/

Electronic Eye Controlled Security System Future Scope The future scope of this project can be augmented by implementing it by using a GSM modem and a microcontroller. The GSM modem can be interfaced to the microcontroller to send and receive SMS to the user in case of burglary. http://www.edgefxkits.com/

Electronic Eye Controlled Security System Conclusion Electronic Eye controlled Security System, device utilizes binary counter as input. It has been successfully demonstrated that, this will serve as a device for providing security. It provides the user with efficient and reliable security system for houses, malls etc; that supports the use of a binary counter which sense the intensity of light through LDR and activating the buzzer indicating a theft. http://www.edgefxkits.com/
