Hey guys hi,
I'm trying to build this circuit (the one given by ronv in post #18 named 'Leak2').
The idea is same i.e. to build a water leak detector for underground pipelines. But i'm planning to add more functionalities to it, like a lcd display to give an indication of the sound frequency being measured so that the operator need not use the headphones all the time.
But that is the later part.
What i am struggling with now is the sensor.
I'm just not able to think how to go about it as i'm dealing with sensors for the first time.
Also i would like to give more details about the problem area which has prompted me to build this project.
A couple of months ago i saw how leak detection is carried out in my city. I was shocked to see a primitive thing like a sounding rod (a listening stick) being used for this purpose. Not only is it a very painstaking way of detecting leaks but also a not so effective one. So i thought of taking this as my academic project. My city looses a lot of water to leaks (about 25% of what it supplies).
I wanted to induce electronics into the same old concept of 'sounding'... as it's called. I was not finding anything satisfactory until i came across ronv's circuit. It was really looking promising.
I'm working on it now but the sensor is something that is bugging me.
Please help.
