The INFWIN LWS10 is a leaf wetness sensor with RS485/Modbus-RTU output. Its resin-sealed plastic body mimics the thermal resistance, shape, and thickness of a real leaf, so wetness readings track how water, ice, or fog would actually collect on foliage. Output interface, power supply, and cable length are configurable via ordering code - the default variant (LWS10-CA002) ships with RS485/Modbus-RTU output, 3.6–30V DC supply, and a 2 m cable.
Wetness measurement value is proportional to the percentage of the sensing area covered with water. LWS10 also reports temperature for compensation. Reverse power protection and built-in TVS/ESD protection are included.
Key Features
- Leaf wetness measurement: Reports the percentage of sensing area covered with water, ice, or fog
- Leaf-mimicking design: Sensing surface replicates the thermal resistance, shape, and thickness of a real leaf
- Temperature compensation: Onboard temperature sensor compensates wetness readings
- FDR measurement technique: Frequency Domain Reflectometry
- Flexible output interface: RS485/Modbus-RTU, RS485 + analog voltage, RS485 + analog current, analog voltage 0–2V, or analog current 4–20mA (see ordering code)
- IP68 waterproof: Fully sealed epoxy resin body
- 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
- Plant disease and bacteria prevention modeling
- Foliage dressing and spray timing
- Scientific research and plant pathology studies
- Greenhouse and nursery monitoring
- Smart agriculture and irrigation scheduling
- LoRaWAN IoT deployments via the Catena-5310 or compatible RS485/Modbus-RTU gateway
Important Notes
- LWS10 mounts using a mounting kit (canopy or stake mount, per installation guidance) rather than being inserted into soil.
- SDI-12 output is listed in the ordering code but is not currently available.
- 4–20mA output requires 12–30V DC supply; the 3.6–30V DC supply option (Code A) is not compatible with 4–20mA output.
- 2.7–16V DC and 2.0–5.5V DC power options are listed in the ordering code but are not currently available.
- When using Active Output mode on RS485, only one sensor should be on the RS485 network to avoid data collision.
