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 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

EMBEDDED SYSTEMS:
Embedded systems are designed to do some specific task, rather than be a general-purpose computer for multiple tasks. Some also have real time performance constraints that must be met, for reason such as safety and usability; others may have low or no performance requirements, allowing the system hardware to be simplified to reduce costs.
An embedded system is not always a separate block - very often it is physically built-in to the device it is controlling. The software written for embedded systems is often called f..................[:=> Show Contents <=:]

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 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 an..................[:=> Show Contents <=:]

e 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 the Ele..................[:=> 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 co..................[:=> Show Contents <=:]
