From the shop's description

ZTS-3002-TR-ECTHNPKPH-N01 Soil Multi-Parameter Sensor Temperature, Moisture, pH, EC, Nitrogen, Phosphorus & Potassium (RS485 Type) The ZTS-3002-TR-ECTHNPKPH-N01 is a high-performance, five-pin multi-parameter soil sensor designed to deliver stable and highly sensitive measurements of soil properties . By accurately measuring the dielectric constant of the soil, it directly reflects the true volume percentage of soil moisture in accordance with current international standards . Engineered for durability, the sensor features a completely waterproof design with vacuum potting and epoxy resin sealing. It is highly resistant to long-term electrolysis and corrosion, allowing it to be safely buried in all types of soil for long-term observation. This sensor serves as an essential tool for studying the occurrence, evolution, improvement, and water-salt dynamics of saline soil.
