TR-HTSE-SDI12 soil moisture / conductivity / temperature sensor has stable performance and high sensitivity. It is an important tool for observing and studying the occurrence, evolution, improvement and water-salt dynamics of saline soil. By measuring the dielectric constant of the soil, it can directly and stably reflect the true moisture content of various soils. The TR-HTSE-SDI12 soil moisture sensor measures the volume percentage of soil moisture and is a soil moisture measurement method that meets current international standards. Suitable for soil moisture monitoring, scientific experiments, water-saving irrigation, greenhouses, flowers and vegetables, grass pastures, rapid soil testing, plant cultivation, sewage treatment, precision agriculture and other occasions.
