Hi @SonoraTechnical, would you be willing to provide the following...
- Parts listing
- Circuit diagrams
- Details (in non technical terms) of the control system. E.g
what and why each component is chosen, it's function in the grand scheme. For example, why a PH sensor? - Any future plans (like measuring nitrates or ammonia, or administering additives)
The reason I ask is, a friend of mine is keen to get into automation. He's good with fish, I'm good with programming & reasonably ok with hardware & so the additional info would give us (and anyone else following) a head start
I will follow your progress. Thanks.
