Description

The Seeed Studio S-Soil MTEC-02 is a high-performance Industrial RS485 Soil Sensor engineered for precision agriculture and environmental research. By integrating three critical parameters—volumetric water content (VWC), temperature, and electrical conductivity (EC)—into a single probe, it provides a comprehensive overview of soil health and nutrient levels. The device utilizes a high-stability stainless steel electrode and is vacuum-potted in flame-retardant epoxy resin, ensuring an IP68 rating for long-term, maintenance-free deployment directly in the ground. With integrated temperature compensation, the MTEC-02 delivers reliable data across diverse soil types and substrates.

Advanced Substrate Analytics

Rugged Anti-Corrosion Build Constructed with special anti-corrosion electrodes to withstand the chemical stress of nutrient solutions and varying soil pH levels.
Standardized Modbus Output Features a universal RS485 Modbus-RTU interface for seamless integration with PLCs, data loggers, and wireless IoT gateways.

Professional Agricultural Scenarios

• Precision Irrigation: Automate water delivery by monitoring real-time VWC levels in commercial greenhouses and farms.
• Salinity Monitoring: Track EC levels to prevent salt accumulation and optimize fertilizer application in soil and substrates.
• Environmental Testing: Perform long-term soil research and moisture tracking in forestry and turf management.
