Product Description

Lufft WS800-UMB Temp,RH,Lightning,Precipitation, Solar Radiation, Air Pressure, Wind

Smart Weather Sensor

Lufft WS800 is the first smart weather sensor from the Lufft WS product family, that comes with a combined measurement of precipitation, solar radiation and lightning detection.

For measuring:

  • Air temperature
  • Relative humidity
  • Precipitation intensity
  • Precipitation type
  • Precipitation quantity
  • Solar radiation
  • Lightning detection
  • Air pressure
  • Wind direction
  • Wind speed
All in One. Aspirated temperature/humidity measurement. Open communication protocol:
  • ASCII
  • UMB
  • SDI12
  • MODBUS
  • Analog outputs in combination with 8160.UDAC
Uses ultrasonic technology for precise wind speed measurement, and is tested in a high-precision wind tunnel, so accuracy is guaranteed.

One external temperature or rain sensor is connectable. WS800-UMB includes lightning detection by an integrated sensor analyzing the radio wave emission of lightnings. It delivers a count of recognized lightnings. The sensor analyses spectrum and wave form of the received signal to suppress the detection of man made electrical discharges.
