1. A soil moisture sensor comprising:
- a sensor body having a horizontally elongated shape formed from a top surface, bottom surface, and a plurality of sides;
a sensor circuit assembly that is horizontally disposed within said sensor body;
an antenna coupled to said sensor circuit assembly and oriented horizontally within said sensor body;
a sensor probe assembly that is connected at a first end of said sensor body so as to be generally perpendicular to said horizontally elongated shape of said sensor body and to extend from an asymmetrically located position on said bottom surface.

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.
