Thank you for this guidance. I have successfully setup this system, almost exactly, to water a single outdoor plant pot whilst I'm on vacation. I popped the electronics in an adapted waterproof project box. The only disadvantage is that the pot is quite deep so the moisture sensor doesn't go deep enough. The pump works great. However, I've learnt a lot from the experience.
