Irrigation system

(That is my anti-static mat that it is sitting on :))

There are plenty of irrigation systems that are connected to the internet, but I enjoy playing around with this stuff so I’m making my own.  I have just started the project, but here is what I have so far.  There was just one on woot today for $164 that looked very polished and intriguing.  There is also one for the Pi that comes with a pre-built open source program that has many of the features I want.  That said, I think I can do it cheaper and get what I want.  I also have plans to add a rain gauge to it to make it work even better, but that’s for another post after I get this project done.


Total cost: $9 + $24 + $2 ≈ $35  (breadboard and wires $2)

User controls requirements:

  • I would like it to be web base.
  • I would like to make this work google calendar.
  • Plug into the weather to determine if they need to be run.
  • I have permanent restrictions which would reduce me to just being able to run a specific two days a week, so I need to run it in the evening if the forecast didn’t pan out.
  • Email notification when a watering is cancelled.
  • I would also like to run specific zones on command so that I can more easily test zones for problems.
  • I want a log of when it ran and for how long on each zone.
  • Each zone needs to be configurable to run for different lengths of time.
  • I’d like an option to skip the next watering with a button click.

I will keep this post updated with my progress.
