energy saving of street lights with light depending resistor. Nowadays‚ human has become too busy and he is unable to find time even to switch the lights wherever not necessary. This can be seen more effectively in the case of street lights. The present system is like‚ the street lights will be switched on in the evening before the sun sets and they are switched off the next day morning after there is sufficient light on the roads. But the actual timings for these street lights to be switched on

Automatic Street Light Control System is a simple and powerful concept‚ which uses transistor as a switch to switch ON and OFF the street light automatically. By using this system manual works are removed. It automatically switches ON lights when the sunlight goes below the visible region of our eyes. It automatically switches OFF lights under illumination by sunlight. This is done by a sensor called Light Dependant Resistor (LDR) which senses the light actually like our eyes.

more times that our street light were turned On even inday time also. This shows that we are wasting much power even it may be saved and supplied for any crop fields for several hours. Here in this project we had designed a simple and cost less circuit using 55 timer ic and LDR (light dependent resistor). Aim of the project: Our main objective of this project is to design and implement a low cost street light controller. This circuit uses a single 555 Timer Ic and LDR (light dependent resistor)

CHAPTER 1 INTRODUCTION This project is mainly used to save power automatically instead of doing manual by using IR sensors The main consideration in the present field technologies are Automation‚ Power consumption and cost effectiveness. Automation is intended to reduce man power with the help of intelligent systems. Power saving is the main consideration forever as the source of the power(Thermal‚ Hydro etc.‚)are getting diminished due to various reasons. Wireless communication

ummary: Did you ever think that how the street lights automatically turn ON in the night and turn OFF automatically at morning? Is there any person who comes to ON/OFF these lights? The following circuit that described below which perform this job automatically. This circuit employed the output from an uncomplicated light/dark activated circuit and oblige a relay in its output which can be further attached to switch ON/OFF a street light and electrical application in a household also. Many of the

Automatic Room Light Controller [pic] INTRODUCTION This Project “Automatic Room Light Controller with Visitor Counter using Microcontroller” is a reliable circuit that takes over the task of controlling the room lights as well us counting number of persons/ visitors in the room very accurately. When somebody enters into the room then the counter is incremented by one and the light in the room will be switched ON and when any one leaves the room then the counter

Automatic street light monitoring using IR and LDR Abstract Street lights are generally switched ON and OFF by the electricity department. A separate person is appointed to take care of these activities without any fail. A part from this if irrespective of the season i.e. whether it is summer or Winter the Street lights are switched ON at the same time in the evening around 6:30 pm and switched OFF at around 6:00 am. And we know that it will be more sunny in summer season with enough light up to 7

radiant light and heat from the sun‚ has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar energy technologies include solar heating‚ solar photovoltaics‚ solar thermal electricity and solar architecture‚ which can make considerable contributions to solving some of the most urgent energy problems the world now faces. Solar power is the conversion of sunlight into electricity‚ either directly using photovoltaic (PV)‚ or indirectly using concentrated
