Lufft Weather Sensor, Electronic Compass, WS-502, Item: 8375-U10

Integrated design with ventilated radiation protection for measuring: Air temperature Relative humidity, Air pressure, Wind direction, Wind speed, Solar Radiation.

Measurement data are available for further processing in the form of a standard protocol (Lufft-UMB protocol). All in One / Aspirated temperature/humidity measurement.

Open communication protocol:

• UMB-ASCII
• UMB-Binary
• SDI-12
• MODBUS
• Analog outputs in combination with 8160-UDAC
• Third-Party-Rain gauge sensors are compatible: 0.1 mm, 0.2 mm, 0.5 mm, 1mm heated and unheated.

One external temperature or rain sensor is connectable. Comes with 10m cable.
