Moisture is the main factor determining the dielectric constant of the soil. Measuring the dielectric constant of soil can directly and stably reflect the true moisture content of various soils. HC3 soil moisture sensor can measure the volume percentage of soil moisture, has nothing to do with the mechanism of the soil itself, is the most popular method of measuring soil moisture in the world. The HC3 Soil Moisture Sensor is a highly accurate, highly sensitive sensor for measuring soil moisture.
