Darkness controlled light switch / Muhammad Salimi Ahmad and Zainuddin Johari

Darkness controlled 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 street light, 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 to 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 is not occur again, the consumer can used this project at their home. This project is applicable to the consumer who is work in early day and back to home lately. When this is occurring, it will make our home save from thieves or any bad people. This is because, this people will no there is someone at home but truthfully there is no one there. This project circuit use a basic electronic devices such as integrated circuit, light dependent resistance, relay, transistors, diodes and resistance. This circuit need to connect to lamp where A.C supply to the lighting load is thus connected via the contact of the relay.
The main futures of this project is to switch ON and OFF the street light automatically without human control. So, we can save the time and electricity for this application. As a result, Darkness Controlled Light Switch is useful for the future application such as to control street light, building light or the others equipment.
