PH probe

[niksunen]

This is exactly same chip that i use first. You might remember that Rob? Unfortunately this kind of analog chips is very bad and not work good at aquarium use. 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 :)
