Finally I can show my progress, I have decided to make modules instead of a single PCB and so far I have:
Module 1: Temperature probes, level probes and dosing pumps
Module 2: Clock and Relays-2
Module 3: Alarm and output for surface fans and led fans
Module 4: Dosing pumps module
Finally I show a picture of the assembly that I have running at this time, the connection is by WiFi
What I need are suggestions for finding boxes for housing the entire assembly, the dosing pumps and the relay module and electrical outlets.
Greetings and apologies for my poor English
