Water irrigation system with wind sensor and method of controlling irrigation
First Claim
1. A water irrigation system, comprising:
- a computer system;
a sensing unit comprising a wind sensor, wherein the wind sensor comprises;
a flow thermistor and a reference thermistor, and wherein the thermistors are configured such that output from the thermistors is a function of wind speed at the flow thermistor; and
a calibration thermistor configured such that output from the calibration thermistor is a function of a temperature of the reference thermistor;
wherein the sensing unit is configured to assess wind speed at the flow thermistor as a function of output from the calibration thermistor and to provide output based on the assessed wind speed to the computer system; and
wherein the computer system is configured to control irrigation of a zone to be irrigated at least partially based on the assessed wind speed.

Abstract
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 wind sensor. The wind sensor may include thermistors. The sensing unit may assess wind speed at one of the thermistors as a function of temperature. The sensing unit may provide output based on the assessed wind speed to the computer system. The computer system may control irrigation of a zone to be irrigated at least partially based on the assessed wind speed. A method of controlling irrigation may include assessing wind speed as a function of temperature, assessing an irrigation need of the zone to be irrigated at least partially based on the assessed wind speed, and controlling irrigation to at least meet the assessed irrigation need of the zone to be irrigated.
