Guys my friends and i have did a project on testing the quality of water..Now the thing is we have bought the project from one shop...I just want to know how the circuit works
It actually glows the green LED light when pure mineral water is detected and glows red Light with a buzz sound when it is salty...
This is all i know about the project ...Am not a expert in electronics and circuits i have just joined engineering ...
Am posting the circuit diagram and am not sure whether is totally correct because one of my senior drawn it by seeing the project..We have used IC LM339
And am a newbie to the forum hope you guys reply soon...
thanks
