Abstract

A system and method for controlling irrigation for controlling irrigation including the transmission of an irrigation data signal including an irrigation instruction. The irrigation instruction may be calculated from various irrigation data including, but not limited to, landscape zone, sun radiation, root depth, soil condition, irrigation efficiency, water source, slope, curbside, evapotranspiration data, and any combination thereof. The system and method may further include the monitoring of irrigation flow and/or of a water meter.

7. The method of claim 6, further comprising identifying the data combination identifier.

8. The method of claim 1, further comprising calculating the preset irrigation schedule from historical irrigation data.

9. The method of claim 1, further comprising:

monitoring an irrigation flow;

transmitting an water flow message;

and receiving the water flow message.

10. The method of claim 1, further comprising monitoring a water meter, transmitting a water meter message, and receiving the water meter message.

11. The method of claim 1, wherein the irrigation data signal is transmitted via a method including transmission over the Internet.

12. The method of claim 1, wherein the irrigation data signal is transmitted via a method selected from the group consisting of optical wireless transmission, radio frequency transmission, optical wire transmission, electrical wire transmission, or a combination thereof.

13. A method of controlling irrigation comprising:

receiving an irrigation data signal; and

adjusting a preset irrigation schedule based upon the irrigation data signal to provide an adjusted irrigation schedule, wherein the irrigation data signal includes an irrigation instruction.

14. The method of claim 13, wherein the irrigation instruction is calculated from irrigation data selected from the group consisting of landscape zone, sun radiation, root depth, soil condition, irrigation efficiency, water source, slope, curbside, evapotranspiration data, and any combinations thereof.

15. A method of controlling irrigation, comprising:

determining an irrigation instruction from irrigation data, and

transmitting an irrigation data signal including the irrigation instruction to a receiver in communication with a controller.

16. The method of claim 15, irrigation data is selected from the group consisting of landscape zone, sun radiation, root depth, soil condition, irrigation efficiency, water source, slope, curbside, evapotranspiration data, and any combinations thereof.

17. A system for controlling irrigation comprising:

a data station;

a first transmitter in communication with the data station,

a first receiver in communication with the first transmitter; and

one or more controllers in communication with the receiver, wherein the first transmitter is adapted to transmit an irrigation data signal including an irrigation instruction to the first receiver.

18. The system of claim 17, wherein the one or more controllers are in communication with at least one sprinkler.

19. The system of claim 17, further comprising at least one additional receiver in communication with the first transmitter and in communication with at least one of the one or more controllers.

20. The system of claim 17, further comprising at least one additional transmitter in communication with the first receiver and in communication with the data station.

21. The system of claim 17, wherein the irrigation instruction is calculated from irrigation data selected from the group consisting of landscape zone, sun radiation, root depth, soil condition, irrigation efficiency, water source, slope, curbside, evapotranspiration data, and any combinations thereof.

22. The system of claim 21, wherein the irrigation instruction further includes a data combination identifier.

23. The system of claim 17, further comprising, a second transmitter in communication with the controller, and a second receiver in communication with the data station, wherein the second transmitter is adapted to transmit a controller information message to the second receiver.

24. The system of claim 23, wherein the controller information message includes a data combination identifier.

25. The system of claim 23, wherein the water flow monitor comprises a flow sensor device coupled to a water meter.

26. The system of claim 25, wherein the flow sensor device is a magnetic sensor to track movement of the water meter'"'"'s arm.
