Soil Moisture Sensor from Decagon Devices.
The soil moisture probes ECH 2 O sensors are capacitive type FDR (Frequency Domain Reflectrometry , Reflectometry frequency domain) that measure the dielectric constant or permittivity to estimate soil moisture content.
The volume fraction occupied by soil water has a huge influence on the dielectric permittivity of soil as its dielectric value (80) is much higher than other soil constituents (mineral soil 4; organic matter, 4, air 1 ).
For this reason, when the amount of water varies soil, soil moisture probes ECH 2 O detect and measure this variation and directly related to the change in water content - VWC. And contrary to what happens with other sensors, soil moisture probes ECH 2 O NO are sensitive to texture and soil EC.
The 10HS sensor measures the soil moisture has a large measuring volume, largest area of influence, and is designed for all types ofapplications in field and laboratory
