Fdr Frequency Domain Method Agriculture Soil Moisture Sensor, Meter for Greenhouse Using

FDR frequency domain method measurement
*The soil moisture was measured by FDR method (frequency domain method),can be obtained soil moisture content.
*FDR method (frequency domain method) measurement of soil moisture is mainly measured with the soil pH, soil density, soil soil, the depth of measurement are closely related.
*The measurement area is a cylinder having a diameter of 7 cm and a height of 7 cm around the center probe with the center probe as the center.
