Does anyone know of a sprinkler system that has some logic built into

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,

Start designing your circuit right now. Make sure you measure moisture
levels in the soil, and at the appropriate depth; no other measure is a good
indicator.
