SOIL SENSOR

This abstract first appeared for US patent application 18968547 titled 'SOIL SENSOR

Original Abstract Submitted

A soil sensor includes a first signal line transmitting a high-frequency electromagnetic wave, and a porous body having a water permeability and a water retention property. The soil sensor further includes a second signal line transmitting a low-frequency electromagnetic wave and facing soil through the porous body, and a ground line arranged on an inside of the first signal line. The second signal line is arranged on an inside of the first signal line and the ground line. Thus, the first signal line and the second signal line are prevented from causing an influence to each other by an electric field generated by one of the two lines.
