Objectives/Aim-To implements automatic and power saving street lightcontroller.

Expected Results- light sensitive street light controller.

Technical Details:

Details of Methodology/ Approach of Development-

Automatic Street Light Control System is a simple yet powerfulconcept, which uses transistor as a switch. By using this system manual worksare 100% removed. It automatically switches ON lights when the sunlightgoes below the visible region of our eyes. This is done by a sensor called Light

Dependant Resistor (LDR) which senses the light actually like our eyes. Itautomatically switches OFF lights whenever the sunlight comes, visible to oureyes.

By using this system energy consumption is also reduced becausenowadays the manually operated street lights are not switched off even thesunlight comes and also switched on earlier before sunset. In this project, noneed of manual operation like ON time and OFF time setting.LDR and micro controller are the main components of the project. Theresistance of light dependant resistor (LDR) varies according to the light

falling on it.

This project uses regulated 5V, 500mA power supply. 7805 threeterminal voltage regulators are used for voltage regulation. Bridge type fullwave rectifier is used to rectify the ac out put of secondary of 230/12V stepdown transformer.

The present system is like, the street lights will be switched on in the eveningbefore the sun sets and they are switched off the next day morning after there issufficient light on the roads. But the actual timings for these street lights to beswitched on are when there is absolute darkness. With this, the power will be

wasted up to some extent. This project gives the best solution for electrical powerwastage. Also the manual operation of the lighting system is completelyeliminated.
