Auto Day-Night Outdoor Power Switching (LDR based)
.Auto Day-Night Outdoor Power Switching (LDR based) is a great and very demanded project. It is the project that every domestic as well as commercial lighting system need. This project save power by preventing wastage of power during day time. Usually, every Switched ON outdoor light at evening, because they need it But in day time, they forget to switch OFF it because it is not noticible in day time. This project automatically detect day and night and switches the light according. Hence, no need to manual switch outdoor light. This is a very nice mini project. This mini project can make by any of following field, namely electrical (EE), electronics (EN), electronics and communication (EC), Computer science (CS), Information technology(IT) etc

Working of Auto Day-Night Outdoor Power Switching
Working of Auto Day-Night Outdoor Power Switching is very simple. It is like that as when light intensity of environment change the current through LDR (Light Dependent Resistor) also changes. This changes in current let the controller circuit to decide where it is Day time or a Night time. And hence, accordingly it turn ON/OFF the outdoor light system, automatically and save energy as well as time.
