How the soil moisture probe works

The AQUAFLEX soil moisture probe uses a process called Time Domain Transmission (TDT). An electrical pulse is sent along a transmission line, which is embedded within the AQUAFLEX sensor, and the electrical field around the transmission line interacts with the surrounding medium. The speed and shape of this pulse is affected by the dielectric properties of the medium. Water has a much higher dielectric constant than most materials that constitute soil, so the presence of water has a profound impact on the electrical signal. This factor enables a soil moisture probe to measure moisture content.
