AI Overview BETA

The Lufft WS800-UMB is an intelligent digital-interface transducer that measures temperature, humidity, precipitation intensity, type and quantity, solar radiation, lightning, air pressure and wind. Its integrated lightning sensor analyses radio-wave emissions, including their spectrum and waveform, to suppress detections from man-made electrical discharges. Environmental monitoring setups can connect an external temperature or rain sensor to the instrument.
