Zephyrus Lite works as a proper anemometer, just using your smartphone microphone!
Dynamic and Average wind speed measuring modes (m/s, km/h) with real time charts, wind direction display (compass) and easy calibration. Last but not least, it is free! Simply the best.
The typical wind range is 1-16 m/s (max 20 m/s): the full scale is limited by the internal mic maximum SPL No sensors required.
