The determination of soil moisture is of great significance for industries such as agriculture, forestry, geology, and construction. Moisture is the main factor determining the dielectric constant of soil. Measuring the dielectric constant of soil can directly and stably reflect the true moisture content of various soils, regardless of the mechanism of the soil itself. It is currently a popular soil moisture measurement method internationally. The TCG-TS soil moisture sensor is a high-precision and highly sensitive sensor for measuring soil moisture.
