Re: Conductivity sensors



I can't quite figure out what parts of the cirtuits are interacting
with each other.

All should have one common probe, like a ground.

Hi Homer, thanks...
I'm not quite sure what you mean by this... all the circuits are on a
single power supply, so they share a ground. The probes themselves are
connected between pins 3 and 6 on the 555. Are you suggesting that I
ought to link these circuits in some other way?
