hi...!!
i am in my 3rd semester of Electrical Telecomm. Engineering...!!
Studying electronics-1...!!
A circuit i found on thre net is attached...!!
It uses transistor "BC548"...in my city this transtitor is not available...!!
I have got "C945" transistor...but the circuit is not working...instead the LED remains on ie. no effect of water level...!!
please help...what alterartions are required...??

no...i have connected the battery as shown in the circuit diagram...ie. +ve terminal in to the water reservoir and to the led and -ve to the emitter...!
and the pin configuration is also different...!!
C945 has base at terminal 3,collector at 2 and emitter at 1...also catered for this too...!!
no result...!!
One of my senior said that resistance values and battery may also effect...??
