The INFWIN MT10RB is a soil moisture 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, power supply, output interface, and cable length are all configurable via ordering code - the default variant (MT10R-BBXAC002) ships with Soil Moisture & Temperature measurement (no EC), 0–100% moisture range, RS485/Modbus-RTU output, 3.9–30V DC supply, and a 2 m cable.

MT10RB uses FDR (Frequency Domain Reflectometry) for soil moisture measurement and 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

Dual measurement: Soil volumetric water content (VWC) and temperature in a single probe
FDR moisture sensing: Frequency Domain Reflectometry — low sensitivity to soil salinity, stable long-term readings
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
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
Greenhouse and nursery soil monitoring
Scientific research and soil science experiments
Environmental monitoring and field data logging
LoRaWAN IoT deployments via the Catena-5310 or compatible RS485/Modbus-RTU gateway

Important Notes

MT10RB (Code 2 = B, Code 4 = X) does not measure EC. Choose MT10RA if EC readings are needed.
Unlike INFWIN's MS10/MS20 series, MT10RB 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.
