Parts list is now included below. This is a quick peek at the hardware portion of the DIY garden automation system I’ve been slowly building over the past year or so. Currently, the system is managing climate control, doing pH and nutrient dosing, fertigation schedule, light cycle, and has flood detection capability. It’s a work in progress and I’ll be sharing more about it as I go.
I’d be happy to hear any comments, questions, or suggestions you might have, and would like to know what you’ve got going on if you’re doing something similar.
