  • Patent number: 4852802
    Abstract: An improved automated irrigation system having localized moisture needs input to the control function. There is a sprinkler head connected to a supply of water under pressure by a pipe having a valve therein. A moisture sensing probe is placed in the soil adjacent the sprinkler head for developing an electrical signal representing the moisture content of the soil surrounding the probe. There is irrigation bypass logic disposed at the probe and operably connected to the valve and the probe for comparing the moisture content of the soil surrounding the probe to pre-established limits and for preventing the valve from supplying water to the sprinkler head when there is sufficient moisture in the soil. A timer controller can be employed to provide operating power to the system only at preferred times for watering. The moisture parameters for watering are adjustable. There is a wirelessly connected version eliminating wires between the probes and the valves.
