Some more microcontroller-friendly pH sensors here -- https://atlas-scientific.com/ph/ https://atlas-scientific.com/ph/
Their datasheets are spectacularly well designed and clear! https://www.atlas-scientific.com/files/pH_EZO_Datasheet.pdf https://www.atlas-scientific.com/files/pH_EZO_Datasheet.pdf
- the__alchemist 6y agoI love the formatting, pictures, and cautions. Good visual flow too. I'm a bit surprised it doesn't go into the technical aspects of what's going on with the transfer functions, which op-amps/ADC are used etc.
- nine_k 6y agoAren't op amps sort of interchangeable here? Provided the correct temperature compensation, they all are highly linear, have a few MOhm input impedance, etc. Same with ADCs; the signal in not particularly high-frequency. What am I missing?
- cbanek 6y agoI've used those and they are fantastic and very easy to wire up!
