The Mysentech MST Sensor is an RS485 Modbus RTU-compatible module for simultaneous measurement of soil volumetric water content, electrical conductivity (EC), and temperature. Designed for integration with industrial PLCs, data loggers, and agricultural monitoring systems, it operates on a wide 3.6-24V DC supply.

Features

  • Triple-Parameter Sensing: Measures soil moisture (0-100%), electrical conductivity (0-20 mS/cm), and temperature (-40°C to +85°C).
  • High Measurement Accuracy: ±3% for moisture and EC, ±0.5°C for temperature.
  • Industrial RS485 Interface: Communicates via Modbus RTU protocol for reliable long-distance data transmission.
  • Wide Operating Voltage: Supports 3.6V to 24V DC with low power consumption (~24mA at 5V).
  • Pre-Calibrated & Weather-Resistant: Factory-calibrated for immediate deployment in outdoor agricultural and environmental applications.

Description

The Mysentech MST Sensor employs advanced sensing techniques to provide accurate, simultaneous readings of three critical soil parameters. Its moisture measurement is based on the dielectric permittivity method (FDR), while the integrated temperature sensor ensures EC readings are temperature-compensated for higher accuracy. The sensor’s robust construction and sealed electronics are designed for long-term burial and exposure to harsh outdoor conditions.

Communication is handled via a standard RS485 interface using the Modbus RTU protocol, making it directly compatible with a wide range of industrial automation controllers, SCADA systems, and IoT gateways. The wide 3.6-24V DC input range allows for flexible power sourcing from solar panels, batteries, or regulated power supplies, suiting remote field deployment.

Key Features

  • Integrated triple-parameter sensing for comprehensive soil analysis.
  • High-precision FDR-based moisture sensing with ±3% accuracy.
  • Temperature-compensated electrical conductivity (EC) measurement.
  • Robust RS485 Modbus RTU interface for industrial-grade communication.
  • Wide operating voltage range (3.6-24V DC) for versatile system integration.
  • Low power consumption design optimized for solar-powered or battery-operated nodes.
  • Factory pre-calibrated, eliminating the need for complex field calibration procedures.
  • Durable, weather-resistant housing suitable for permanent outdoor installation.

Applications

  • Precision agriculture and irrigation scheduling systems.
  • Soil science research and environmental monitoring networks.
  • Greenhouse and nursery substrate moisture and nutrient management.
  • Golf course and turf management for optimized water usage.
  • Landslide and slope stability monitoring via soil moisture sensing.

Frequently Asked Questions

What is the operating voltage range for the Mysentech MST Sensor?

The sensor module operates on a wide DC voltage range from 3.6V to 24V. This flexibility allows it to be powered by common sources like 5V logic supplies, 12V battery systems, or 24V industrial PLC power rails, making it suitable for both portable and fixed installations.

How do I communicate with this sensor and what protocol does it use?

The sensor communicates via a standard RS485 serial interface using the Modbus RTU protocol. You will need an RS485 transceiver or converter (like an RS485-to-USB adapter) to connect it to a computer or microcontroller. Standard Modbus function codes are used to read the moisture, EC, and temperature registers.

Is the sensor pre-calibrated, and can it be re-calibrated in the field?

Yes, the Mysentech MST Sensor is factory pre-calibrated for general soil types and is ready for immediate use without field calibration. For applications requiring extreme precision with specific soil compositions, advanced users may reference the manufacturer's documentation for potential calibration procedures via Modbus commands.

What is the measurement accuracy for soil moisture and temperature?

The sensor provides soil moisture readings with an accuracy of ±3% across its 0-100% range. The integrated temperature sensor has a high precision of ±0.5°C across its operational range of -40°C to +85°C. The EC measurement accuracy is also ±3%.

Is this sensor suitable for permanent outdoor installation?

Yes, the sensor is designed with a durable, weather-resistant housing intended for long-term outdoor use in agricultural and environmental monitoring applications. For permanent installation, it is recommended to bury the sensing probe at the desired depth while ensuring the cable gland and connector junction are properly sealed from moisture.
