hi dear friends,

i am currently working out a ph-measurement-set - that is based on Arduino

well there are lots of tutorials, explanations out there:

i found a neat one: See:

pH meter Arduino, pH Meter Calibration, DIYMORE pH Sensor, pH Sensor Arduino Code, pH of liquids pH meter Arduino, pH Meter Calibration, DIYMORE pH Sensor, pH Sensor Arduino Code, pH of liquids - YouTube

the gus use a DFrobot pH Sensor Kit:
DFrobot pH Sensor with Arduino, working, calibration, and pH value of different liquids:

DFrobot pH Sensor with NodeMCU ESP8266 for water quality monitoring:

Arduino Nano

Arduino Uno:

pH Sensor Kit DIYMORE

pH Sensor Kit DFrobot

well - i like this setup - meanwhile - some of the folks have used a ESP32

but iguess that i can do this with Arduino Uno or so

look forward to hear from you

hello and good day dear Railroader - many many thanks for the quick reply - this looks pretty awesome i like it very much.

keep up the awesome place here - this is a outstainding forum

on a sidenote>

I note that the Atlas Scientific EZO has a pH resolution of +/-0.002 - i do not really need that high resolution? It costs $42 and seems to require a separate probe that we will have to buy. The circuit board looks a bit rough. The websites that I've searched for this product say it is not available at present.
The DFRobot is about the same price but comes with a probe. The pH resolution is only +/-0.1 which is probably OK for most people (only the user can decide that) and the whole assembly look very professional. I note that this product is still available.

Well what would you do / note i only want to test liquids like water coffee cola and such ones.
