Intelligent Environmental Sensor For Irrigation Systems

摘要

The invention provides a regulator system for regulating the operation of an irrigation system which is responsive to user programmed information. It has a control element for issuing watering control signals to an irrigation system, having at least one of (i) a duration programming device for programming a minimum amount of time and a maximum amount of time for the suspension of watering by the irrigation system, and (ii) a user adjustable temperature programming device for programming a minimum allowed temperature for initiating a watering period by the irrigation system. It further has an irrigation system interface for connecting said control element with the irrigation system. It also has a switch for conveying the control signals from the control element to the irrigation system via the irrigation system interface, for either permitting or prohibiting watering by the irrigation system, responsive to the control signals generated by and received from the control element.

主权项

1. A system for regulating an irrigation system comprising:
a sensor unit configured for operation at a remote location comprising:
a wireless transmitter that wirelessly transmits data; and,a hygroscopic sensor assembly that measures a first amount of rain and a second amount of rain without adjustment; said second amount of rain being larger than said first amount of rain; a control module configured for operation local to an irrigation controller, comprising:
a transceiver that wirelessly receives said data wirelessly transmitted by said sensor unit;a module control circuit in communication with said transceiver;a user interface in communication with said module control circuitry and configured to allow user-adjustment of an irrigation interruption threshold that is triggered by measurement of said hygroscopic sensor assembly of either said first amount of rain or said second amount of rain; wherein said control module is connectable to said irrigation controller to interrupt an irrigation schedule.
