The INFWIN MS10 is a soil moisture and temperature sensor with RS485/Modbus-RTU output. Its resin-sealed plastic body with stainless steel rods inserts directly into soil for long-term in-situ measurement. Output interface, moisture range, power supply, and cable length are all configurable via ordering code - the default variant (MS10-AACA002) ships with RS485/Modbus-RTU output, 0–100% moisture range, 3.6–30V DC supply, and a 2 m cable.

MS10 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
Flexible output interface: RS485/Modbus-RTU, RS485 + analog voltage, RS485 + analog current, analog voltage 0–2V, analog current 4–20mA, or SDI-12 (see ordering code)
Configurable moisture range: 0–100% or 0–50% VWC; higher resolution and accuracy in the 0–50% range
Soil-type calibration: Configurable soil type via Modbus register (Mineral, Sand, Clay, Organic) for improved accuracy. Can also be factory-calibrated for specific soils.
IP68 waterproof: Fully sealed with epoxy resin body and stainless steel rods; 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.
Active output mode: Sensor can push data at a configurable interval without master polling (RS485 variants)
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
Sports turf and golf course irrigation management
LoRaWAN IoT deployments via the Catena-5310 or compatible RS485/Modbus-RTU gateway

Important Notes

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.
For buried installation at depth, drill a 45 mm diameter hole at about 10° to the vertical using an auger, then insert and backfill.
4–20mA output variants require 12–30V DC supply; the 3.6–30V DC supply option (Code A) is not compatible with 4–20mA output.
When using Active Output mode on RS485, only one sensor should be on the RS485 network to avoid data collision.
