Abstract
According to some exemplary embodiments, the present disclosure is related in general to a soil moisture monitoring system comprising a first PVC pipe holding one or more sensing units, a top of the first PVC pipe mated to a “T” intersection, and a base of the “T” intersection mated to a rodent resistant cord. The first PVC pipe is generally round in shape with one or more flat surfaces of approximately six inches in length, each flat surface at an approximately 90 degree angle relative to a next closest flat surface. Each of the one or more sensing units further comprises a controller communicatively coupled between two antennas. In most exemplary embodiments, four sensing units may be vertically stacked on the first PVC pipe and configured to transmit eight separate directional radio frequencies into nearby dirt, each of the eight separate directional radio frequencies vertically spaced six inches apart.
