Light Dependent Resistor Real-life example
Light Dependent Resistor Real-life example Security System Controlled by An Electronic Eye This security system controlled by an electronic eye project is based on photo sensing arrangement. The proposed system uses a 14-stage ripple carry binary counter to sense the intensity of light using LDR. The o/p makes a relay and buzzer for the required action. This project is very useful to deter burglars from malls, banks and shops. This project or systems uses a light dependent resistor. When light falls on the LDR sensor, then the resistance of the sensor decreases, which lead to activate an alarm to give an alert to the user. This project is suitable in the application of providing security system for different types of area or place like lockers, cash boxes, malls, shops. The circuit of this project is placed inside of the cash box in malls or inside of the lockers in such a way that, when a burglar opens the cash box or locker and uses a torch light to sear...
