1. A soil moisture sensor comprising:
- a sensor casing having a first side with a generally flat shape and a second side opposing said first side and having a generally curved shape;
a first plurality of elongated sensor electrode pins located on and extending out from said second side of said sensor casing;
a second plurality of elongated sensor electrode pins located at said second side of said sensor casing and spaced apart from said first plurality of elongated sensor electrodes;
wherein said second side has a curve that substantially matches an interior of a 4.25 inch hole.

Abstract
A wireless soil sensor includes a curved surface and at least two groups of sensor-pin electrodes. A tine-catching block is disposed within the sensor body, near a top of the sensor to protect against aeration tools damaging components of the sensor. The electrical circuitry and the battery are separately potted in an epoxy material and oriented vertically, creating a central gap through which an incoming aeration tine is directed.

9. A method of installing a moisture sensor comprising:
-
creating a cylindrical hole in soil having a diameter of about 4.25 inches; placing a soil moisture sensor in said hole; orienting a first group of sensor pins at a first distance from a top of said soil; orienting a second group of sensor pins at a second distance from a top of said soil, said second distance being longer than said first distance; and
,pressing a curved surface of said soil moisture sensor into a curved wall of said cylindrical hole;
said curved surface having a curved shape corresponding to and being reciprocal to a portion of said cylindrical hole having said diameter of about 4.25 inches. - View Dependent Claims (10, 11, 12, 13)
