Patent ID: 8924032

Claim:
An irrigation system comprising: a stand alone weather station including at least one environmental sensor configured to detect an environmental condition of an irrigation site; a soil moisture sensor configured to detect a level of soil moisture; and an irrigation controller operatively in communication with the soil moisture sensor and the stand alone weather station, the irrigation controller comprising a plurality of user inputs that enable a user to enter a watering schedule including a run time and to manually adjust a percentage adjustment value of a percentage adjustment feature, a computer processor operatively connected to the plurality of user inputs, a memory operatively connected to the computer processor, and a plurality of switches operatively connected to the computer processor to turn a power signal ON and OFF to a plurality of valves that deliver water to a plurality of sprinklers, wherein programming stored in the memory accepts input from the user via the plurality of user inputs to implement the watering schedule such that during said run time, the computer processor operates ones of the plurality of switches to deliver water to ones of the sprinklers to irrigate an irrigation site and to implement said percentage adjustment feature to change the run time of the watering schedule by the percentage adjustment value, wherein the programming further automatically increases or decreases said percentage adjustment value in response to the environmental condition, and wherein the computer processor automatically inhibits irrigation when the level of soil moisture is above a threshold.
