of the lighting system is completely eliminated.
In our project we are using LDR, which varies according to the amount of light falling on its surface, this give an indication for us whether it is a day/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. Bri..................[:=> Show Contents <=:]

pasted withcopper track-layout.

• Connection pin is passed through the hole and is soldered.
WORKING
• When light falls on the LDR then its resistance decreases which
results in increase of the voltage at pin 2 of the IC 555.
• IC 555 has got comparator inbuilt, which compares between
the input voltage from pin2 and 1/3rd of the power supply voltage
• When input falls below 1/3rd then output is set high otherwise
it is set low.
• Since in brightness, input voltage rises so we obtain no positive
voltage at ..................[:=> Show Contents <=:]

The project presented here is to on/off the street lights automatically when the particular person is out of reach or if he forgot to switch off the lights.
Here we are mainly using 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 ope..................[:=> Show Contents <=:]

to ADC of PIC. PIC is stand for peripheral interface controller.

ADC is inbuilt in PIC. The function of the ADC is to convert the analog signal to digital signal. From this digital signal the light in the environment can be Monitored. If the darkness increase that is at night time the lamp will be Automatically on. At day time the brightness is less so the light will be Automatically OFF.

Relay is used for the ON\OFF the light. Here we are using the Electromagnetic relay12v supply is need to drive this relay. Operating voltage of The PIC is 5V this get from power supply unit. Oscillator ..................[:=> Show Contents <=:]

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.

This system c..................[:=> Show Contents <=:]
