han 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 consists of a microcontroller,
ADC converters, power supply, LCD display board, relay
Circuit and step down transformer. This system requires LCD interfacing program and ADC converting programs; here the software called keil is used in compiling the programs. The logic behind this automatic operation is that it compares the recorded light intensity with the specified value in the program and act like wise

d in k ohm/second and for current LDR types it is more than 200k ohm/second. The recovery rate is much greater in the reverse direction, e.g. going from darkness to illumination level of 300 lux, it takes less 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 cadmi..................[:=> Show Contents <=:]

t of data and program memory, tended to be:
Costly:
The microprocessor system had to satisfy the data and program requirements so, sufficient RAM and ROM are used to satisfy most applications .The peripheral control equipment also had to be satisfied. Therefore, almost all-peripheral chips were used in the design. Because of these additional peripherals cost will be comparatively high.
An example:

• It has resistance of about 1mega ohm when in total darkness,
but a resistance of only about 5k ohms when brightness illuminated.
• It responds to a large part of light spectrum.
TRANSFORMER
For 9v ac power supply we can use step down transformer in order to convert 230 volt to 9 volt.

. There is no light then the resistance value is change. From this resistance change the voltage variation can be obtained this value is given 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 t..................[:=> 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..................[:=> Show Contents <=:]
