I've built a forward looking, adaptive sprinkler system: it downloads the 5
days local forecast and algorithmically builds an irrigation plan based on
the day's high temperature, the length of the day, and if its going to rain
in the near future. There is no need for rain, temp, humidity sensors (which
are expensive) as the information is all included in the local forecast.
Looked at from outside, it sometimes looks like its really 'smart': for
example, it once didn't water for two straight rather warm days, and I was
beginning to get worried. On the morning of the third day we had a SERIOUS
rain. No hardware can get you that kind of 'intelligence', and it does a
better job of optimizing the water usage, in my opinion.
