SN-300SD-TR-N01 RS485 Soil Moisture Sensor
The SN-300SD-TR-N01 is a high-precision RS485 soil moisture sensor designed for seamless integration into agricultural monitoring systems, environmental research stations, and industrial PLCs. It delivers accurate volumetric water content readings via a robust, fully sealed probe suitable for long-term burial or submersion.
Features
- RS485 digital interface with Modbus protocol for reliable, long-distance communication.
- Corrosion-resistant alloy electrodes ensure stable performance in various soil salinity conditions.
- Fully sealed, IP68-equivalent waterproof housing for permanent underground or underwater installation.
- Fast response time (<1 second) for real-time soil moisture monitoring.
- Wide operating voltage range (12-24V DC) compatible with industrial power supplies.

The SN-300SD-TR-N01 soil moisture sensor operates on the proven principle of frequency domain reflectometry (FDR), measuring the dielectric permittivity of the soil to determine its volumetric water content. Its specially treated alloy electrodes minimize the effects of corrosion and electrolysis, ensuring measurement stability and longevity even in saline environments. The sensor’s output is digitally transmitted via an RS485 interface, providing excellent noise immunity for integration over long cable runs into SCADA, PLC, or data logger systems.
Housed in a robust, fully sealed enclosure, the sensor is designed for permanent installation, capable of withstanding continuous burial or submersion. Its plug-and-play probe design simplifies deployment, while its low power consumption (<20 mA) makes it suitable for solar-powered remote monitoring stations. The sensor is calibrated using soil drying methods for high accuracy across a broad range of soil types.
