Durable Soil Moisture and Temperature Sensor Seeed 314990620 Featuring MODBUS RTU RS485 Protocol
Product Overview
The RS485 Soil Moisture & Temperature Sensor (S-Soil MT-02A) is a high-reliability, high-stability sensor designed for long-term environmental monitoring. It integrates both soil moisture and soil temperature sensing capabilities into a single unit, utilizing the MODBUS-RTU RS485 protocol for universal compatibility. With a wide power supply range and IP68 rating, this sensor is robust, anti-corrosion, and built to withstand demanding applications. Its design ensures stable measurement of soil volumetric water content (VWC) by measuring the dielectric constant, conforming to international standards and making it suitable for various agricultural and environmental monitoring scenarios.
