ABSTRACT

The automatic street light controller is basically operated according with the light intensity. The simple concept about this operation is that, whenever there is less intensity of natural light (i.e. less than 1.5v) then the light gets automatically on. Similarly when the light intensity is high (i.e. 5v) then the light get automatically off.

than 10ms to reach a resistance which corresponds with a light level of 400 lux. A LDR may be connected either way round and no special precautions are required when soldering.
• Darkness: Maximum resistance, about 1Mohm.
• Very bright light: Minimum resistance, about 100 ohm.
The LDR is a variable resistor whose resistance decreases with the increase in light intensity. Two cadmium sulphide (cds) photoconductive cells with spectral response similar to that of the human eye. The cell resistance falls with increasing light intensity. some of its features:
• High reliability.
• Ligh..................[:=> Show Contents <=:]

ay/night time. We have placed IR sensors in both sides of the road, which can be controlled by Micro controller (AT89C51).The IR‘s will be activated only on the night time. If any obstacle crosses the IR, automatically particular light will be ON, for few seconds.
In our project we use regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac out put of secondary of 230/12V step down transformer.

OBJECTIVES
1. To save the electric power.
2. To reduce the man power.
PRINCIPLE
It works under the principle , when the light falls on the LDR
depending upon the value of the resistance the light is turnedON and OFF.
ABSTRACT
• Needs no manual operation for switching.
• When there is a need of light it automatically detects that weather there is need of light or not.
• Light is switched OFF at night and ON at the morning hours.
LDR
• It is a special type of resistance whose value depends on the

sing the sensor for detecting the light LDR (light dependent Resistor). The characteristics of the LDR are the resistance is very high when it is in dark and resistance is low when it is in light.
The Microcontroller is used to control the whole system, it monitors the sensor output, and according to the sensor condition the street lights are operated. The whole program is written in Embedded C and burned into the microcontroller ROM.
The AT89C52 is an 8-bit microcontroller with 8k bytes of flash ROM, 256 bytes of RAM is preferred due to its quick programming and ease of..................[:=> Show Contents <=:]
