PROJECT DESCRIPTION

The main objective of this project is to design a system where light will remain on only from dusk to dawn.

As per–unit electricity cost is very high these days, so it is advisable to judiciously use electricity. Places like colleges, housing complexes, highways, industries and parks spread across large area where more light is required during night.

This system provides a solution for these places, as dusk to dawn system the lights will be automatically on at dusk and switch off at dawn. Thus, saving energy and money also human intervention is also eliminated.

This system is based on an 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 light during dusk and switches off at dawn. 555 timer controls the load through a TRIAC

Q & A
Q:  What is automatic dusk to dawn?
A:  Light will automatically switch on in the evening and switch off in the morning time by sensing the daylight.
Q:  Which sensor is used?
A:  LDR is the sensor used.
Q:  What is LDR?
A:  LDR or light dependant resistor is a special type of resistor whose resistance changes when light falls on it.
Q:  What to do when the lamp fails and what is the maximum lamp rating that can be used?
A:  If the lamp fails one can use any lamp or bulb which is used in homes up to 100W. We suggest you to go for low watt bulbs.

I decided to buy from you, because my friend suggested me. I bought RK-kit, and liked Plug & Play concept of readymade kit.
