The WS Series compact weather sensors are designed for reliable and maintenance-free measurements in hydrology, meteorology and weather-dependent applications where durability, precision and operations in different moderate climatic conditions and wind speed up to 100 mph (45 m/s) are required.
The compact devices allow for single or all-in-one measurements of up to 7 parameters such as

  • Wind speed
  • Wind direction
  • Temperature
  • Humidity
  • Air-pressure
  • Rainfall
  • Radiation

All sensors have been tested and approved against following environment conditions:

  • High and low temperature ranges
  • Humid weather (humidity and ingress protection)
  • Windy and coastal environments (vibration and salt spray sustainability)
  • Wind speed measurement up to 100 mph (45 m/s)
  • Low costs of installation and total costs of ownership
  • Corrosion-resistant polycarbonate material, solid structure and rugged design
  • Product portfolio to suit best to automatic weather monitoring
  • Build-In data processing and algorithm
  • Universal and selectable interfaces and protocols such as SDI-12 or RS 485 (MODBUS-RTU, ASCII, NMEA 0183)
  • Easy integration into 3rd party systems
  • Low power consumption for solar power packages
  • No moving parts and maintenance-free with high IP grade 66
  • Sustainability and high accuracy at entire wide temperature operating range from -40 to +158°F (-40 to + 70 °C) (non-heated versions)
  • Metric and imperial units
  • Unheated versions: Operating measuring and deployment temperature range from -40 to +158°F (-40 to +70 °C)

WeatherSens WS is especially suitable for hydro-meteorological and agrometeorological applications by one sensor design and construction, e.g. for

  • Automatic weather stations - hydro
  • Smart cities, urban areas and municipalities
  • Road weather monitoring
  • Power grid transmission stations
  • Agrometeorological stations such as ETo or irrigation stations
  • Photovoltaic farms
  • Building automation
  • Airfield and helicopter landing platforms
