Soil moisture / conductivity / temperature sensor has high performance stability and sensitivity, and is an important tool to observe and study the occurrence, evolution, improvement and water and salt dynamics of salt soil. By measuring the dielectric constant of the soil, it can directly and stably reflect the true water content of various soils. The soil moisture sensor measures the volume percentage of soil moisture and is measuring soil moisture in accordance with current international standards. It is suitable for soil moisture monitoring, scientific experiments, water-saving irrigation, greenhouse, flowers and vegetables, grassland and pasture, soil quick testing, plant culture, sewage treatment, fine agriculture and other occasions.
