Hi, yes, actually an interesting article. But just a month ago, I came across an overview of an interesting program. Where it explains very well how to get water from the environment. Here is the site https://ex-reviews.com/self-help/water-freedom-system-review/ where you can find more information about this program.
I like the visual aspect along with the water conservation theme. Is the unit water proofed or water resistent? I assume there is an enclosure to prevent the Arduino board from getting wet.
I really like this visual water project. I'm working on similar project of water pool you can see here https://thehomebeasts.com/
