I am trying to make a liquid conductivity sensor. Basically I tried to use a simple two electrode device to measure the resistance/conductivity but I have to much stray current as well as a ground probe in the tank of liquid. Both of which cause erroneous readings in my sensor.
I thought an induction based sensor would work better. Can anyone tell me how to make one, or suggest a better method?
