Anemometer

The Anemometer BT15i is a device for measuring wind speed between 0.4 and 35 m/s. 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.

The following experiments can be performed with the Anemometer:
• 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 an Anemometer and a compass to determine wind direction.

The Anemometer BT15i can be directly connected to the analog BT inputs of the CMA interfaces.

Technical specifications of the sensor are descibed it its User's guide.
