With an Assembled & Tested PCB

DIY kit comes with an Assembled and Tested PCB ensuring 100% output guarantee. Includes hardware for assembling project from scratch. Fully supported by elaborate documentation, audio visuals and tools to independently carry out the project work.


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.

Q & A
Q:  What is electronic eye?
A:  It is a secured monitoring system
Q:  How does it function?
A:  It functions by sensing light in a closed chamber
Q:  Where can I use it?
A:  You can use it with precious items like cash box, jewel box, lockers etc.
Q:  What is the formula for calculating smoothing capacitor value?
A:  There is some approximated formula .Peak to peak ripple voltage = Load current in amps / (2*line frequency in hertz *capacitance in farads). But as rule of thumb for 1 A current 1000uF is best. Thus it is load dependent.

I was searching my project Pre Stampede Monitoring and Alarm System using PIC Microcontroller find in Edgefx in Google.
I found my project Title so decided to buy that project
The kit got delivered to me on time with all the right components.
I have purchase through online

I was searching for Major or Minor Projects, Electronics Projects in the Google and I Found Edgefx.Before I placed the order I have called for technical clarifications and I got good response so decided to buy from Edgefx. I like the two kits provided in my Project.The kit got delivered in time with all the right components.Technical person from Edgefx helped me a lot in project.I will refer Edgefx to my seniors and friends also.
