Wireless Wind Speed Measurement Based on Three–Axis Ultrasonic Anemometer
Abstract
In this paper, a three-axis ultrasonic anemometer is presented which uses six ultrasonic transducers to obtain the wind speed, wind direction, etc. Every two transducers are used as transmitter and receiver of a short sequence of pulses. The time of flight is taken by the ultrasonic sound to travel from the transmitter to the receiver. This can be used to determine the three dimensional vector components of wind—u, v and w. From these components, the resultant wind speed and direction can be obtained. The developed anemometer is intended to be used in the environment monitor demand of tethered aerostat and airship. Also it can support autonomous navigation for a scale model sailboat.
