This project deals with “Development of an Embedded system for Automatic street light controlling with Sun Tracking” using micro controller
AT89C52 and Light sensor named as light dependent
resistor (LDR).
In our daily life we are observing street lights still on in day time also. In this type of
conditions the electricity (power) is wasted. This project deals with how to
avoid this condition using embedded system.
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 Micro controller 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 micro controller ROM.The AT89C52 is an 8-bit micro controller with 8k
bytes of flash ROM, 256 bytes of RAM is preferred due to its quick programming
and ease of use.
