A LDR is a device which changes its resistance depend up on the light intensity. Whenever light falls on the LDR, electrons in valence band are excited and move to the conduction band. The movement of free electrons and holes causes the current flow in the LDR with decrease in resistance.
offers 8,162 solar street light sensor and controller products. About 40% of these are led street lights, 19% are street lights, and 1% are sensors. A wide variety of solar street light sensor and controller options are available to you, such as ce, ccc, and bv.

The ASLCS (Automatic Street Light Control System) based Light intensity & traffic density, in the todays up growing countries will be more effective in case of cost, manpower and security as compare with today's running complicated and complex light controlling systems.
LDR based Automatic Street Light using Microcontroller. Street light or flood light which is completely automatic makes life easy. Nowadays powerful LEDs are using as flood lights. They have many advantages over old lights like least power consumption, long life, DC operated etc.
The assembling of the entire solar LED street light system can be connected using all the above components which use sun energy to give the power to the LED lamps fixed on street poles. Solar Powered Led Street Light with Auto Intensity Control Project Kit by
AUTOMATIC STREET LIGHT CONTROL SYSTEM (MINOR PROJECT) ABSTRACT Automatic Street Light Control System is a simple yet powerful concept, which uses transistor as a switch. By using this system manual works are 100% removed. It automatically switches ON lights when the sunlight goes below the visible region of our eyes.
utilization) control of street light using various electrical as well as electronic components. The circuit named auto intensity control of street light with solar tracker is designed using microcontroller along with real time clock (RTC) and Light Dependent Resistance (LDR).
The block diagram of street light system as shown in Figure.2.1 consists of microcontroller, LDR, and IR sensor. Figure 2.1 Block diagram of automatic solar street light intensity control circuit By using the LDR we can operate the lights, i.e. when the light is available then it will be in the OFF
The main parts in the project are sensors, Solar Panels and monitors.Two kinds of sensors will be used which are light sensor and motion sensor. The light sensor will detectdarkness to activate the ON/OFF switch, so the streetlights will be ready to on. In the other hand the motion sensor will detect turn movement to activate the streetlights.
Download Automatic Street Light PPT with PDF Report: We are going to discuss here advantages, disadvantages and applications of Automatic Street Light and advantages are: Photo resistors change light into electricity and are not dependent on any other force, LDRs are delicate, inexpensive, and readily obtainable devices, They are small enough ...

The heart of this circuit is a LDR (Light Depended Resistor) which is connected as a potential divider with a 56K resistor. The drop across LDR is used for switching the transistor. Solar led street lighting systems are the advanced versions of this ordinary automatic street light controller. Solar table lamp circuit for your home; Remote ...
Solar Powered LED Street Lighting with Auto Intensity Control Ch Kavitha, Swathi, Satyaprakash, Vinitha Abstract— The project is designed for LED based street lights with an autocontrol that uses solar power from photovoltaic cells. A -intensity
Commercial grade LED solar powered street lighting systems manufactured in the USA by SEPCO providing a great solution for streets, roadways, and highways. Each solar lighting system is manufactured to meet the needs of the client and takes into account the local weather and solar insolation.
based automatic control systems. Our project presents an automatic street light controller using light dependent resistor(LDR). By using this system manual works are removed. The street lights are automatically switched ON when the sunlight goes below the visible region of our eyes. It automatically switches OFF the street
Solar energy based automatic street light controller INTRODUCTION Solar powered automatic street light controller is an very efficient device which regulated the street light working. It automatically turns on when there is dark at the dusk time and turns off at the dawn when the sun is out.
An introduction: Needs no manual operation for switching ON and OFF. When there is a need of light it automatically switches ON. When darkness rises to a certain level then sensor circuit gets activated and switches ON and when there is other source of light i.e. daytime, the street light gets OFF.
