Soil Multifunctional 6 in 1 Sensor – RS485 Output

The Soil Multifunctional 6 in 1 Sensor is an integrated soil monitoring device designed for accurate measurement of soil temperature, moisture, pH, and NPK nutrient levels. It operates on 12–24V DC and communicates via RS485 interface for stable long-distance data transmission. With IP68 protection and fast response time under 1s, it ensures reliable performance in outdoor agricultural environments. Suitable for greenhouses, orchards, rice fields, and precision agriculture systems.
