Description

We developed a simple and low cost wind velocity sensor based on a small microphone. In this paper, we first present the mechanism of the sensor, i.e., how to find the wind velocity from the output wind noise of a microphone by successfully suppressing the influence of other sounds existing in the environment. Then, we demonstrate the effectiveness of the sensor by showing the application to the real-time animation of a tree swaying in real wind.
