Smart Weather Sensor, WS-800, Item: 8381-U01

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

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. One external temperature or rain sensor is connectable.
