PRODUCT DETAIL
Lufft Ultrasonic Weather Sensor with Solar Pyranometer, WS-501, Item: 8375-U01.
Integrated design with ventilated radiation protection for measuring: Air temperature Relative humidity, Air pressure, Wind direction, Wind speed, Solar Radiation. Integrated design with ventilated radiation protection.
Relative humidity is measured by means of a capacitive sensor element; a precision NTC measuring element is used to measure air temperature. Ultrasound sensor technology is used to take wind measurements. Measurement data are available for further processing in the form of a standard protocol (Lufft-UMB protocol).
Open communication protocol:
Available with low-power setting for remote stations with solar power. One external temperature or rain sensor is connectable.
