Monitor VWC in potted soil
Measure volumetric water content in soils and soillless medias with a range of salinities.
This wireless soil moisture sensor is built to monitor volumetric water content (VWC) for an accurate measurement of all soils and soilless medias with a wide range of salinities. Using real-time data from soil sensors, farmers can adjust and tailor a granular approach to irrigation and nutrient delivery. Custom alerts can provide insights on which crops are in need of irrigation, and which are in need of drainage to prevent the damaging effects of overwatering including standing water compromising root development, overaccumulation of salts, root rot, fungus and mildew.
The EC-5 determines volumetric water content (VWC) by measuring the dielectric constant of the media using capacitance/frequency domain technology.
70 MHz frequency minimizes salinity and textural effects, making this sensor accurate in almost any soil or soilless media.
