The 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.
Model: 8381-U01
From the WS product family of professional intelligent measurement transducers with digital interface for environmental applications. Integrated design with ventilated radiation protection for measuring:
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.
