Weather Based Landscape Irrigation

Source: Texas A&M AgriLife Research and Extension Center – Dallas

An ET controller automatically adjusts the amount of water applied to your landscape based on weather conditions. The “smart” ET controller receives radio, pager or internet signals with evapotranspiration information to replace only the moisture your landscape has lost to heat, humidity and wind. Nonsmart controllers are set, or not, and seasonally adjusted by a person.
