The INFWIN MT10RA is a soil moisture, EC (electrical conductivity), and temperature sensor with RS485/Modbus-RTU output. Its resin-sealed plastic body with PCB sensing rods inserts directly into soil for long-term in-situ measurement. Moisture range, EC range, power supply, output interface, and cable length are all configurable via ordering code - the default variant (MT10R-ABCAC002) ships with Soil Moisture, EC & Temperature measurement, 0–100% moisture range, 0–20000 µS/cm EC range, RS485/Modbus-RTU output, 3.9–30V DC supply, and a 2 m cable.

MT10RA measures soil moisture by FDR (Frequency Domain Reflectometry) and EC by AC excitation, giving three readings - moisture, conductivity, and temperature - from a single probe. It offers low salinity sensitivity, minimal soil disturbance, and IP68 waterproofing for direct burial. Reverse power protection and built-in TVS/ESD protection are included.

Key Features

Triple measurement: Soil volumetric water content (VWC), EC, and temperature in a single probe
FDR moisture sensing: Frequency Domain Reflectometry — low sensitivity to soil salinity, stable long-term readings
AC excitation EC sensing: Direct soil conductivity measurement with temperature compensation (0–50°C)
PCB sensing rods: Printed-circuit sensing element rather than solid stainless steel rods
Configurable moisture range: 0–100% or 0–50% VWC; higher resolution and accuracy in the 0–50% range
Configurable EC range: 0–5000, 0–10000, or 0–20000 µS/cm
Output interface: RS485/Modbus-RTU, RS485 + analog voltage, or analog voltage 0–2V (see ordering code)
IP68 waterproof: Fully sealed with epoxy resin body; suitable for direct soil burial
Wide operating range: −40°C to +85°C operating temperature; suitable for outdoor and agricultural deployments
Reverse power protection: Built-in TVS/ESD protection
RS485 Modbus-RTU protocol: Standard Modbus register map; configurable slave address, baud rate, parity, and stop bits. Factory defaults: address 1, 9600 bps, 8N1.
Configuration utility: SensorOneSet software included for sensor configuration via RS485
Cable length: 2 m standard; custom lengths available

Applications

Agricultural irrigation control and smart farming, including salinity-aware irrigation scheduling
Greenhouse and nursery soil monitoring
Scientific research and soil science experiments
Environmental monitoring and field data logging
Fertigation and soil salinity management
LoRaWAN IoT deployments via the Catena-5310 or compatible RS485/Modbus-RTU gateway

Important Notes

Unlike INFWIN's MS10/MS20/MEC10/MEC20 series, MT10RA does not offer a 4–20mA analog current or SDI-12 output option - only RS485/Modbus-RTU and 0–2V analog voltage (standalone or combined) are available.
The sensor rods are sharp for ease of insertion - handle with care and follow installation precautions.
Do not pull the sensor out of soil by its cable. If resistance is felt during insertion, stop and re-insert at a new location to avoid hitting stones.
When using Active Output mode on RS485, only one sensor should be on the RS485 network to avoid data collision.
