1. A soil moisture system comprising:
- a soil moisture sensor;
a receiver unit having a wireless transceiver communicating with said soil moisture sensor;
an irrigation interrupt value stored in said soil moisture system;
said irrigation interrupt value displayable and adjustable on a user interface of said soil moisture system as a percentage of a maximum soil moisture content of a region of soil; and
,an interruption mechanism interrupting irrigation controlled by an irrigation controller;
said interruption mechanism interrupting irrigation based on said irrigation interrupt value and a present soil moisture value transmitted from said soil moisture sensor.

Abstract
In one embodiment, the present invention is directed to a soil moisture sensor for interrupting an irrigation schedule of an irrigation controller. The moisture sensor comprises a relatively flat body with two lower electrodes and two lower anchoring barbs. A receiver receives moisture readings from the sensor and compares moisture data to a predetermined moisture interrupt value or limit, over which irrigation is interrupted.

11. A soil moisture system comprising:
-
a soil moisture sensor; a receiver comprising a user interface and a wireless transceiver that communicates with said soil moisture sensor; an irrigation interrupt value that is user-selectable via said user interface and is stored in said receiver;
said irrigation interrupt value being a numerical percentage of a field capacity of a region of soil;an interruption mechanism located in said receiver and causing interruption of irrigation controlled by an irrigation controller;
said interruption mechanism triggering irrigation interruption when a current soil moisture value measured with said soil moisture sensor is higher than said irrigation interrupt value. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A soil moisture system comprising:
-
a soil moisture sensor; a receiver comprising a user interface;
a wireless transceiver, and an irrigation controller interface; and
,said receiver interrupting irrigation by said irrigation controller when a current soil moisture value measured by said soil moisture sensor exceeds an irrigation interrupt value; wherein said irrigation interrupt value is expressed as a percentage of a maximum moisture content level of a region of soil. - View Dependent Claims (19, 20)

21. A method of controlling soil moisture, comprising:
-
displaying an irrigation interrupt value on a soil moisture sensor receiver;
said irrigation interrupt value being expressed as a percentage of a maximum moisture content of a region of soil;receiving periodic soil moisture values wirelessly transmitted from a soil moisture sensor; interrupting irrigation by an irrigation controller attached to said soil moisture sensor receiver when one of said periodic soil moisture values is greater than or equal to said irrigation interrupt value.
