What I'm wanting to do is install something that automatically waters 4 flower boxes, one Japanese fire maple (???), and my front lawn. Lawn is pretty small, takes me 15 min to cut with push mower.

Is there a device that I can use for this? I'm thinking of something that has sensors in the soil and turns on each 'area' when the soil is to dry and needs water. Is this possible? Suggestions on products?

Yard/boxes see sun in the morning and is partially shaded. My house faces east so yard/boxes are shaded after noon.

This is my project for the winter/spring for the yard, so I'm doing my research now.
