It works somewhat fine if you put probe to drinking glass and some water there. But in aquarium there is so much "noise" that you cannot get accurate readings, and values you get shifts all the time.
My solution was to throw that cheap analog chip to garbage can :D And buy atlas-scientific stamp and whiteboxlab isolated carrier board. https://www.whiteboxes.ch/shop/isolated-...ier-board/
After those i get very steady and accurate readings :)
Hi Niksu, I remember you used an analog circuit but thought it was a different style, either way they are all the same. I think if it was isolated it would likely work better but in my opinion not worth the cost as they just aren't very good as you know. Glad that Atlas circuit is working much better for you. :) The board you have is the one I recommend because it's very easy to connect to the controller unlike those shields that hold 2-4 circuits.
