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.
