The Anemometer ML90s is a device for measuring wind speed. The sensor is a propeller-type anemometer with the axis of rotation parallel to the direction of the wind.

The number of revolutions is counted via a magnet and reed sensor and is converted to wind velocity.

**Technical specifications:**

- Range: 0.4 .. 35 m/s
- Resolution: 0.1 m/s
- Maximum sampling rate: 10 Hz

Can be used in experiments to:

- measure the wind speed of air generated by a variable speed fan
- investigate why wind speed is slower over land than it is over the ocean
- use together with a compass to determine wind direction.
