Abstract

A system for providing irrigation control is provided. The system includes a processor configured to calculate an offset to an evapotranspiration (ET) value and an irrigation system configured to receive the offset from the processor and provide appropriate irrigation adjustment based on the offset. The offset is calculated based on the ET value and the ET value has been previously provided to the irrigation system.

a processor configured to calculate an offset to an evapotranspiration (ET) value, the processor further configured to create or alter an irrigation program based on the offset; and

an irrigation system configured to receive the irrigation program from the processor and provide appropriate irrigation adjustment based on the irrigation program;

wherein the offset is calculated based on the ET value and the ET value was used to create or alter a prior irrigation program previously provided to the irrigation system.

5. The system of claim 4 wherein the processor is further configured to encrypt the irrigation program;

and

wherein the irrigation system is further configured to decrypt the irrigation program received from the processor.

6. A system for providing irrigation control, comprising:

a plurality of non-local data sources for providing data;

a processor configured to receive data from one or more of the plurality of non-local data sources and calculate an offset to an evapotranspiration (ET) value for an irrigation area that is non-local with respect to the plurality of non-local data sources, the processor further configured to create or alter an irrigation program based on the offset, wherein the offset is calculated based on the ET value; and

an irrigation system configured to receive the irrigation program from the processor and provide appropriate irrigation adjustment for the irrigation area using the irrigation program.

7. The system of claim 6 wherein the processor is further configured to encrypt the irrigation program for transmission to the irrigation system;

and

wherein the irrigation system is further configured to decrypt the irrigation program received from the processor.

8. A system for providing irrigation control, comprising:

a plurality of non-local data sources for providing data;

a processor configured to receive data from one or more of the plurality of non-local data sources and calculate an offset to an evapotranspiration (ET) value for an irrigation area that is non-local with respect to the plurality of non-local data sources, the processor further configured to create one or more components constituting an irrigation program based on the offset, wherein the offset is calculated based on the ET value; and

an irrigation system configured to receive the one or more components from the processor.

9. The system of claim 8 wherein the irrigation system is further configured to use the one or more components received from the processor to derive the irrigation program and provide appropriate irrigation adjustment based on the irrigation program.

10. The system of claim 8 wherein the processor is further configured to encrypt the one or more components for transmission to the irrigation system;

and

wherein the irrigation system is further configured to decrypt the one or more components received from the processor.

11. A system for providing irrigation control, comprising:

a plurality of non-local data sources for providing data;
