Nice project. A couple quick questions regarding the Krylon paint:

  1. Does it sufficiently protect PLA for outdoor use (UV and possibly being buried)?
  2. You mentioned spraying the entire sensor. Does that affect the sensing capability if sprayed on the part that goes in the soil?

All the best from frozen Minnesota. I'll test this setup on a few houseplants but plan on using it in an irrigation system IF winter ever ends here.

01) What is that cable?
02) Whats the farthest length you used to communicate over I2C with the water sensor?
