ABSTRACT:
The main goal of this project is to design a framework where light will remain on only from dusk to dawn.
As per– unit electricity cost is high nowadays, so it is advisble to judiciously utilize electricity. Places like colleges, housing complexes, highways, industries and parks spread cross large area where all the more light is required during night.
This framework gives a solution for these places, as dusk to dawn system the lights will be automatically on at dusk and switch off at dawn. Along these, saving energy and money also human intercession eliminated.
This framework depends on a LDR, it senses the change in intensity of light and its output changes accordingly. The output of the LDR is fed to a 555 timer in astable mode, which switches on dusk and switches off at dawn. 555 timer controls the load through a TRIAC.
