Testing Protocol for Landscape Irrigation Soil Moisture-Based Control TechnologiesPublished by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.org ASAE ANSI/ASABE S633 May 2020Keywords: : Bypass switches, Controllers, Irrigation, Landscape, Smart water application technologies, SMS, Soil moisture sensors, SWAT, Turf 1 Scope This standard defines a procedure to test a soil moisture sensor and interface device‘s response to changes in soil moisture conditions in a media that simulates soil. The test procedure covers soil water content (volumetric) and soil water tension (matric potential) sensors. The standard provides a method, using two different media, two water salinities, and three different water depletion levels, to determine if the sensor and associated interface device will enable/disable an irrigation event at preset or selected soil water values.
