ND-LWS Leaf Wetness Sensor
What is the ND-LWS? The ND-LWS is a leaf wetness sensor that detects condensation, dew and rainfall on a leaf-like surface — the critical input for plant disease prediction models. With sub-microsecond resolution and clear thresholds (LW < 0.11 dry, ≥ 0.11 wet, ≥ 0.27 totally wet), it powers outdoor remote monitoring, smart agriculture, plant disease and infection prevention and greenhouse / soil-less plantation deployments connected to the yDoc ML-525 datalogger.

Applications
Where the ND-LWS is used
Outdoor remote monitoring
Long-term canopy wetness monitoring in remote orchards and field stations.
Smart agriculture
Site-specific spraying decisions based on actual leaf wetness duration.
Plant disease prevention
Drive Decision Support Systems for fungal pathogen risk in vines, fruit and field crops.
Greenhouses & soil-less
Canopy condensation monitoring for climate control and disease management in protected cropping.
Integration
Powered by the yDoc ML-525 datalogger
The ND-LWS connects directly to the yDoc ML-525 datalogger. The yDoc powers the sensor, schedules measurements, stores readings locally and transmits them to the Sensor-Online platform via 4G/LTE-M, NB-IoT, LoRaWAN, satellite or Ethernet — with up to 10 years of battery life.
