时域反射土壤水分传感器
Saline or heavy clay soils can push capacitance probes off calibration; TDR copes far better. Using pulse travel time along a 10–100 cm waveguide, this sensor reads volumetric water content at 0.1% resolution in under a second, with ±1–2% accuracy after calibration. Choose SDI-12, RS-485 or a cable-tester setup for column or field research.
