ND-CWS2 Road Weather Station with Radiation Shield (RWIS)
What is the ND-CWS2? The ND-CWS2 is a high-precision winter road maintenance sensor with non-contact infrared road-surface temperature, air temperature, relative humidity and calculated dew point — all protected by a high-accuracy radiation shield. Designed for outdoor remote monitoring, road weather information systems (RWIS), winter road maintenance, frost alarming, ice alert and smart agriculture deployments connected to the yDoc ML-525 datalogger.

Key parameters
What the ND-CWS2 measures
Road-surface temperature
–40 to +70 °C, ±0.5 °C, IR non-contact
Air temperature
–40 to +70 °C, ±0.4 °C, shielded
Relative humidity
0–100 % RH, < ±3 % accuracy
Dew point (calculated)
–40 to +70 °C, ±1 °C — critical for frost prediction

Applications
Where the ND-CWS2 is used
Road weather (RWIS)
Decision support for snow ploughing, salting and traffic safety operations on national road networks.
Winter road maintenance
Surface and air temperature plus dew point for proactive icing prevention.
Frost & ice alert
Trigger warnings the moment surface conditions point to imminent freezing.
Bridges & tunnels
Site-specific monitoring where road surface temperature deviates from general weather forecasts.
Smart agriculture
Frost alarming for orchards, vineyards and high-value crops.
Integration
Powered by the yDoc ML-525 datalogger
The ND-CWS2 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.
