I want to use Raspberry Pi + Codesys as a Chemistry Controller for my pool. The Idea is to measure PH and REDOX Potential with Electrodes and control Pumps for injection of necessary chemistry.
I found following RPI modules, which are suitable for measurements:EZO ORP
, EZO PH
from Atlas Scientific and Tentacle T3
to host those on RPi. The boards have I2C Interface and supplied with source code on Python.
How do you think would it be possible to make the readings via Codesys? Or perhaps someone did driver already? Or is there any other alternative measurement modules available?
