First transformer will be 220 v alternating current into below 12 v or 12 v dc ( Communication is also can, but it is best to dc) , after ab is the pressure on both ends of the voltage, R1 is used to limit the R2 photoresistor on both ends of the voltage ( Triode breakdown voltage is 0. 4 v or 0. 7 v, so work in the whole circuit voltage at the ends of the photosensitive resistance R2 should keep a change of number) , in addition to the R1 is used to limit the whole circuit voltage, and work to provide voltage circuit is white. R3 is used to adjust the LED electric current, thus protecting the LED. < / p > parameters are uncertain, according to what material do you want to determine. Circuit connection well after debugging.
