Abstract
In today’s world, walkway lights are very much required in populated regions. Due to the busy lifestyle of humans, switching operations on walkway lights are not carried out on time, and a huge amount of electricity is being wasted. In the present system, it is observed that walkway lights are not turned OFF even when there is an ample amount of light after sunrise and are turned ON even before sunset. Even in timer based street light control systems, the ON and OFF time differ noticeably during sunny and rainy days. To overcome these problems, an automatic walkway light controller is designed. The project aims to eliminate the manual operations and to design an energy-efficient automatic walkway light controller using a light-dependent resistor (LDR). The Light Dependent Resistor (LDR) senses the light actually like our eyes. It automatically switches OFF lights whenever the sunlight comes visible to the sensor. This project demonstrates the working of the transistor in a saturation region and cut-off region. The working of the relay is also known. Implementation of this project encourages digital work. Light-dependent resistor, a photocell has been used as the transducer to convert light energy into electrical energy. The central dogma of the circuit is that the change in the voltage drop across the light-dependent resistor on illumination or darkness switches the transistor between the cut-off region or saturation region and switches OFF or ON the lights. The result was an efficient automatic lighting system for walkway that is highly economical, reliable and requires very little maintenance
