Low-Error Soil Moisture Sensor Employing Spatial Frequency Domain Transmissometry
A new type of soil moisture sensor using spatial frequency domain transmissometry (SFDT) was evaluated. This sensor transmits and receives ultrawideband (1 to 6 GHz) radio waves between two separated antennas and measures the propagation delay time in the soil related to the dielectric constant. Thi...
