Abstract:
1. A method for adaptive irrigation control, the method comprising: obtaining a plurality of real-time soil measurements from a plurality of wireless sub-surface sensors at least three inches below the surface, the plurality of real-time soil measurements comprising a real-time soil moisture value, a real-time soil temperature value, a real-time soil salinity value and a real-time moisture percolation value; monitoring at an adaptive wireless irrigation interrupter a plurality of watering schedules for a set period of time established by an irrigation controller for a land area without end-user intervention wherein the adaptive wireless irrigation interrupter is in wireless communication with each of the plurality of wireless sub-surface sensors concerning at least the real-time soil measurements in a particular soil area; and adjusting a scheduled irrigation based on the plurality of real-time soil measurements and at least one of seasonal, weather, climate and soil conditions; wherein the adaptive wireless irrigation interrupter generates a two dimensional map, with a soil dielectric constant on one axis and a soil conductivity on the other axis, for received power for all antenna configurations from a wireless sub-surface sensor of the plurality of wireless sub-surface sensors, wherein the map is downloaded on a regular schedule to the wireless sub-surface sensor of the plurality of wireless sub-surface sensors and the wireless sub-surface sensor reviews the map for the antenna configuration that provides the highest received power at the adaptive wireless irrigation interrupter for the current conditions.
