Description
The 4-in-1 Soil Nutrient Sensor is an advanced multi-parameter soil monitoring device designed to measure soil moisture, temperature, EC (electrical conductivity), and pH using a single robust instrument. Built with five stainless-steel probes, this sensor offers high accuracy, fast response, and long-term durability in harsh outdoor environments.
Sealed with flame-retardant epoxy resin and rated IP68 waterproof, the sensor is corrosion-resistant, electrolytic-resistant, and ideal for long-term field deployment. Users can choose between multiple output options—0–5V, 0–10V, 4–20mA, or RS485 Modbus—for seamless integration into any industrial or agricultural monitoring system.
This 4-in-1 sensor eliminates the need for buying multiple soil sensors and is suitable for precision agriculture, smart irrigation, environmental monitoring, and scientific research.
