IRRIGATION CONTROLLER INTEGRATING MANDATED NO-WATERING DAYS, VOLUNTARY NO-WATERING DAYS, AND AN EMPIRICALLY-DERIVED EVAPOTRANSPIRATION LOCAL CHARACTERISTIC CURVE

摘要

A convenient, easy-to-use, water-saving, and labor- saving FROG smart irrigation controller is provided, which determines the appropriate water budget for the specific geographic region based on the preloaded ETo Local Characteristic Curve and preloaded mandated and voluntary watering restrictions for the specific geographic location, with consideration given to the reduction in watering days, the increase in soil watering depth, and the day of year. Once set, the FROG provides incremental adjustments over the course of the year; the homeowner no longer needs to re-set the watering program seasonally to comply with local mandated and voluntary watering restrictions. Compliance is automatic and obligatory, meeting the water saving goals of the local water authority.
