ESO-H 200 implements dedicated sensor functionality capable of measuring the volumetric water content (VWC) of the soil. Measure VWC from 0 to 100% (VWC of saturated soils is generally 40 to 60% depending on the soil type) and allows accurate measurement of all soils and soilless medias with a wide range of salinities.

ESO-H 200 is connected to the EMOS 200LH via one of its Sensor Interfaces. The ESO-H 200 is based on an ultra-low power sensing unit. Measurement value are provided via analog voltage. EMOS measures and processes the value.
