Plover is a portable TDR (Time Domain Reflectometry) soil moisture meter of moisture, temperature and electrical conductivity. Minimal footprint meter equipped with a Bluetooth Low Energy, which can be easily operated by a smartphone in the field. Tiny sensors follow true TDR principle, the upper frequency of the analyzing needle pulse is about 1.5 GHz. Special designed sensor body with ultimate low heat conductivity avoid the parasite "thermal bridge" effects on distribution of soil moisture in the probe’s sensor vicinity.
