Abstract
A sensor housing having a body for housing a soil moisture sensor arrangement with sensors arranged within and along the length of the housing, the body is shaped so that there is a continuous taper from the head end having the larger outer diameter to the inserted end having the smaller outer diameter, and the volume of the opening created by an auger in the ground will provide a matching volume for the sensor housing of a predetermined volume such that the entire tapered outer surface of the sensor is adjacent the ground along the full length of the created opening. The sensors include at least a first capacitive element, and a second capacitive element that has a maximum outer diameter smaller than the maximum outer diameter of the first capacitive element.
