Lufft WS800 Weather Sensor

Lufft WS800 Weather Sensor

The Lufft WS800 Weather Sensor is a compact, all in one weather sensor designed for professional meteorological, road weather, and environmental monitoring applications. Using advanced radar, ultrasonic, and digital sensor technology, the WS800 measures multiple weather parameters with high accuracy from a single device.

The Lufft WS800 Weather Sensor is ideally suited for permanent outdoor installations where reliable, low maintenance weather data is required in real time.

ALL IN ONE SMART WEATHER SENSOR DESIGN

The Lufft WS800 Weather Sensor combines multiple meteorological measurements into a single rugged housing, reducing installation complexity and overall system cost.

Integrated measurements include precipitation type and intensity, wind speed and direction, air temperature, humidity, air pressure, and visibility related parameters. This all in one design eliminates the need for moving parts and separate sensors.

LUFFT WS800 PARAMETERS

Parameters include:

  • Temperature
  • Relative humidity
  • Air Pressure
  • Wind Direction
  • Wind Speed
  • Precipitation
  • Precipitation Intensity
  • Precipitation Quantity
  • Solar Radiation
  • Lightning Strikes

ADVANCED PRECIPITATION AND WEATHER DETECTION

The WS800 uses Doppler radar technology to accurately detect precipitation type and intensity.

Rain, snow, mixed precipitation, and freezing rain are identified in real time, supporting applications where precise surface condition awareness is critical. Radar based measurement ensures reliable performance even in harsh weather conditions.

ULTRASONIC WIND MEASUREMENT

Wind speed and wind direction are measured using ultrasonic technology with no moving parts.

This provides fast response, high accuracy, and long term stability while eliminating mechanical wear. Ultrasonic wind measurement makes the Lufft WS800 Weather Sensor suitable for exposed and high wind environments.

RELIABLE DATA FOR ROAD WEATHER AND INFRASTRUCTURE

The Lufft WS800 Weather Sensor is widely used in road weather information systems and smart infrastructure monitoring.

By combining precipitation, wind, temperature, humidity, and pressure data, the WS800 supports decision making for traffic safety, maintenance planning, and operational control.

FLEXIBLE COMMUNICATION AND SYSTEM INTEGRATION

The Lufft WS800 Weather Sensor supports multiple communication interfaces and protocols for easy integration into existing monitoring systems.

  • RS 485 communication
  • SDI 12 output
  • Modbus protocol support
  • Configurable data output formats

This flexibility allows seamless connection to data loggers, telemetry systems, and cloud based platforms.
