i want to read the electrical appliances state.so i need to convert 230v to 5V dc.Is there any easiest way to convert voltage from 230 to 5V.

230V AC to 5V,1A Dc converter

A series resistor ( 2 x 100k in series ?) shunt diode ( 1N4148?) and optocoupler would allow you to sense the presence of 240vac safely....
