Abstract: An interactive irrigation system exchanges information between an irrigation controller and a distal computer, between the irrigation controller and a user, between the user and the distal computer, and between the distal computer and a third party. The information is preferably exchanged over an Internet communication system. The exchanged information includes the following: irrigation scheduling; quantity of water applied to the landscape at the user location, which is compared to ETo values; warnings to users when potential problems with their irrigation systems are detected; and other irrigation information that is useful to the user or a third party.
Abstract: The present invention provides a warning system comprising: a weather measuring device that measures a current weather condition; and a storage device that stores historical weather data; a microprocessor that is programmed to receive the current weather data from the weather measuring device, compare the current weather data to the historical weather data, generate a warning signal if the current weather data varies from the historical weather data by at least a given amount, and send the warning signal to an individual.
Abstract: A method of controlling irrigation to an irrigated area comprises: extrapolating an irrigation schedule at least partly as a function of at least two user entered data points; and executing the irrigation schedule by an irrigation controller. The user entered data points can all be entered at the same time or over a period of time. Furthermore, two or more user entered data points may be entered for the same date. Additionally, the user entered data points may be deleted. A warning is preferably displayed to the user (a) when a user-entered data point is projected to result in an irrigated area not receiving adequate water to meet a plant's water requirement, or (b) when an irrigated area is projected to receive excessive water.

Abstract: An irrigation system includes a plurality of modules, each of which operates a plurality of irrigation stations, a master controller that controls the plurality of modules, and a user interface that receives a user input that identifies to the master controller which of the plurality of irrigation stations are active. The master controller may comprise a dedicated irrigation controller, a personal computer, or other suitable device. The plurality of modules may advantageously use decoder chips, and may be disposed in the irrigation controller or physically separate from the irrigation controller. The user interface will preferably be disposed in the master controller but may be disposed in a device physically separate from the master controller. The operation of the plurality of irrigation stations is at least partly affected by information transmitted from the microprocessor disposed in the master controller.
Abstract: The present invention provides systems and methods in which a microprocessor, disposed in an irrigation controller, is programmed to adjust an irrigation schedule according to a condition of a plant being irrigated. The adjustment to the irrigation schedule may be to the entire irrigated site or only to a portion of the irrigated site. The irrigation schedule may be at least partly derived from ETo data and may be from current ETo data, estimated ETo data or historical ETo data. The condition may be plant establishment, plant maturity or plant health.
Abstract: An irrigation management system comprises a microprocessor that determines a mathematical relationship between a calculated watering requirement and an applied irrigation amount; and an output device that provides a result of the mathematical relationship to at least one of an irrigation user and a third party. Preferably the calculated watering requirement is at least partly derived from ETo data. Additionally, the calculated watering requirement is at least partly derived from a crop coefficient value and an irrigation efficiency value. Preferably the applied irrigation amount is derived from data obtained from a flow meter and preferably from a utility meter that was initially installed at the irrigation site. Water pressure can also be measured and communicated to the irrigation user and/or third party.
Abstract: An irrigation controller that is capable of making daily adjustment of irrigation duration based upon historical, environmental, and or received information. The irrigation controller can automatically skip days and make changes to account for daily and seasonal environmental changes. Such automatic determination is advantageous to minimize the need of the operator intervention to make seasonal change as well as providing irrigation savings, and ensures deep irrigation. The simplified user interface and control allows for a change made at any time of the year to effect the remainder of the year to provide the best balance of minimal or no user interface, irrigation conservation.
