Monitoring my hydroponics
Mike:
The nice thing about those EZO boards is that you can put a bunch of different probes and control boards on them and they are still the same interface. Also learning how much hydroponics is a engineers dream. So much you can measure and account for if you want.
So for future expansion I'd add another of those. I've already got additional 1-wire connections.
Priced it out and a 2 layer board is insanely cheap. So may just get this one printed and work on V2 later.
Mike:
Well, now I've bought a EC probe. But, didn't do the fully isolated daughter board. And I think I'll go with that for both in the future. Saves a lot of room.
Mike:
And all that I just found this: https://www.atlas-scientific.com/kits/wi-fi-hydroponics-kit/
Not cheap but probably cheaper than what I've spent so far. Oh well, need some hobby I guess
Mike:
I'm finishing up version two. Going with a 4 layer board to make life easier. I put version 1 p for review on reddit and got some feedback to add some decoupling capacitors to the EEPROM but I honestly have no idea how to size those and I don't feel like doing a ton of math for this hobby project.
Mike:
Going with the 4 layer version 2 using through-hole only. The surface mount stuff was hurting my brain too much.
Order placed to print it. $7 for 5 boards (only need 1 but min order is 5) and then like $30 for the shipping.
