The soil moisture sensor determines volumetric water content (VWC) by measuring the dielectric constant of the media using capacitance/frequency domain technology. It minimizes salinity and textural effects, making it accurate in almost any soil or soil-less media. Factory calibrations are included for mineral soils, potting soils, and rockwool. The sensor will need a 24VDC power supply to operate (Part # FGD-0070)
- Operating Temperature Range -40 ° to 140 °F | -40 ° to 60 °C
- Accuracy ±6% VWC with generic calibration for supported growing media up to 65% VWC, above which accuracy lessens. Increased accuracy can be achieved with a medium-specific calibration.
- Connection Hardwired
- Settling Time 4 seconds
- Scale 0 - 100% VWC (Volumetric Water Content)
- Dimensions 3.5” x .27” x .7” x | 89mm x 18 mm x 7mm
- Sensor Series 4-20mA
