Darkness control light switch is a circuit that used to ON and OFF the switch automatically depend on the light. Generally, this circuit is used in the streetlight, at the house lamp and also in the light at the garden where it can ON and OFF automatically. Today we known several people are unwilling to work. So according o this time, include the modem technology used, we tried to create this project to make it very easier in a lifetime. This project is an automatically function and is very useful if we connected to the house lamp.
This is because the concept that we used now is wasting time and electricity. So, to make this problem does not happen again in the future, we can apply this project. The consumer can use it at their home. This project is applicable to the consumer who is work in early day and went home late. If we use it, it will make our home save from thieves or any bad people. This is because if the light switch ON automatically it can make that house look like there are someone in the house but truthfully there is no one in there. These project circuits use a basic electronic device such as integrated circuit, light dependent resistance, relay, transistors, diodes and resistor. This circuit need to be connecting to lamp A. C supply to the lighting load is thus connected via the contact of the relay.
The main future of this project is to switch ON and OFF the streetlight automatically without human control. So we can save time and electricity by using the application of this project. As a result, darkness controlled light switch is useful for the future application such as control street light, building light or others equipment
