WIRING DIAGRAM:

Its 100% my own design..... :)

PROCEDURE:

Relay is simple 220 volt , You can use one contact i have used multiple by soldering all in parallel
to increase life of relay. Sensor is simple LDR circuit make it by Toner transfer method, If u dont want to run on UPS just skip relay portion from wiring diagram.
