Abstract
The present invention provides a multitude of embodiments for landscape water conservation with automated water budgeting or seasonal adjustment. Water budget automation may be implemented within an irrigation controller, by means of an add-on or a plug-in to the controller, or broadcast from a central location. The environmental data used for automated water budgeting may be historical including ambient temperature, wind, solar radiation, relative humidity, soil moisture, soil temperature, or evapotranspiration, or combinations thereof, or with a combination of current sensor data. The automated water budgeting may be accomplished with a percentage accumulation method which adjusts watering intervals and schedules, or on a daily percentage basis. In addition, government based restricted watering schedules may be combined within all the above embodiments to provide additional flexibility for water conservation.
