So I actually have a bunch (6) of Raspberry Pis deployes around my house, in rooms, garage, basement, furnace room, etc.,, that have an Arduino nano hung off them to manage MQ5, MQ7, MQ135, and MQ2 analog sensors for watching various air quality stuff because the Pis can't do analog sensors without an A2D converter. That is why I'm thinking I'm going to add on PH and TDS sensors eventually. I may even add CO2 and get sensors for that, but they are significantly more expensive, and I'm not sure my grow is big enough to need them, based on current ridiculously awesome results... That being said, I may add it anyway, because I love coding stuff. I also think it might be incredibly cool to code up a stepper motor and sonar distance sensor to auto adjust light height...Id love to incorporate some SBC’s into my next grow. Have you used microcontrollers as well, there are so many sensors that could be useful for growing.
The current iteration for environmental controls is specific to the hardware, specifically the Digital Loggers Web Power switch, and it doesn't have a lot of error handling yet, but as that develops, I am definitely planning to open source it all.
