频域反射土壤水分传感器
Irrigation managers and turf teams who want soil water data around the clock usually start here. Buried at 10–200 cm, the FDR sensor reports volumetric water content over 0–100% via analog, SDI-12 or Modbus output, on 3–12 VDC low-current power. Accuracy is ±2–3% once calibrated to your soil. Tell us your logger or controller model.
