Lufft WS800-UMB Smart Weather Sensor
Key features
 
    	
  • Measuring wind direction and speed insusceptibly to bird nesting thanks to roofed construction
    • 	
  • First and only all-in-one compact weather sensor with lightning detection
    • 	
  • Built-in data pre-processing, universal interfaces and selectable output protocols
    • 	
  • Maintenance-free operation – no moving parts that can wear out
    	
  • Compatible with many commercially available Met/HydroMet data loggers and PLS systems thanks to an open communication protocol
    • 	
  • Suitable for all climate zones; also for solar-powered automatic meteorological stations
    • 	
  • Integrated heater that can be switched on if there is danger of frost
 
From the WS product family of professional intelligent measurement transducers with digital interface for environmental applications. Integrated design with ventilated radiation protection for measuring: Air temperature, relative humidity, precipitation intensity, precipitation type, precipitation quantity, solar radiation, lightning detection, air pressure, wind direction and wind speed. One external temperature sensor is connectable.
