Unlike many other soil moisture sensors the Hydra Probe arrives at a moisture reading by simultaneously measuring both factors, that largely influence this parameter: the dielectric constant and the conductivity. The dielectric constant is most indicative of water content while the conductivity is strongly dependent on soil salinity. The high frequency electrical measurements indicating the capacitive and conductive properties of soil are then directly related to the soil’s moisture and salinity content while a thermistor determines soil temperature. All three parameters are delivered via an SDI-12 interface. The A506 SDI-12 interface is sold separately.
