as I was working I was thinking about this, on how people would plug in a probe etc to monitor/control their PH, co2, salinity, temp etc.
my other concern was how small the screen is I was hoping to have a screen at least 6x6 inches so it could be easily seen from a distance. Maybe something we could look into?
Dark PM me to please I have an idea I want to run by you that is kinda off topic.
