RING & TECHNOLOGY

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 consists of a microcontroller,
ADC converters, power supply, LCD display board, relay
Circuit and step down transformer. This system requires LCD interfacing program and A..................[:=> Show Contents <=:]

mw to .5w. Though very sensitive to light, the switching time is very high and hence cannot be used for high frequency applications. They are used in chopper amplifiers. Light dependent resistors are available as discs 0.5cm to 2.5cm. The resistance rises to several Mega ohms under dark conditions.
The below figure shoes that when the torch is turned on, the resistance of the LDR falls, allowing current to pass through it is shown in figure.

7. Write data to I/O device and output the result of processing to O/P device.
NECESSITY OF MICROCONTROLLERS:
Microprocessors brought the concept of programmable devices and made many applications of intelligent equipment. Most applications, which do not need large amount 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 ..................[:=> Show Contents <=:]

haracteristics 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 use.
COMPONENTS:
Power supply board

1. 8051 pcb
2. solar panel
