Does anyone know of a sprinkler system that has some logic built into it?
I was thinking of a control system that would make use of some
transducers that sense moisture levels and ensure that moisture levels
stay within a certain range. The moisture level combined with the time of
day would determine whether the sprinkler system is activated. Is there
already a product out there to do this, or should I start designing my
circuit now?

Thanks,

The only one that I'm aware of is the rain sensor, and they usually
don't work very well.
