Water irrigation system with moisture gauge and method of controlling irrigation

摘要

A water irrigation system may include a computer system, a sensing unit, an irrigation controller, and/or a water delivery system. The sensing unit may include a moisture gauge. The moisture gauge may include a capacitor coupled to a collector. The sensing unit may assess an amount of moisture in the collector and provide output that is a function of the amount of moisture in the collector to the computer system. The computer system may control irrigation of a zone to be irrigated at least partially based on the assessed amount of moisture in the collector. A method of controlling irrigation may include assessing an amount of moisture in a collector near or in a zone to be irrigated and controlling irrigation at least partially based on the assessed amount of moisture in the collector.
