Quality and cheap PH probe for raspberry PI projetc

Growroom Design

As the title suggest I’m looking to by a good quality PH probe to incorporate into a Raspberry PI. Prefer American or European versus Chinese crap, any suggestions from the makers/hackers among us. I don’t grow commercially so cost is a factor to some extent, but I do expect quality.

Thanks for any useful comments or suggestions.

Take a look at Atlas Scientific.

They are not the “cheapest” but their probes are reliable and the circuitry relatively noise free. They have options for a PI or other eval kit interfaces along with source examples…

Oh, 15% off using SPRING2019 until May 10th.
