A Low-Cost Ultrasonic Wind Speed and Direction Measurement System

"\"The paper deals with a low-cost transducer that. implements an improved technique for wind speed measurement. in open air. The instrument is a 2-axis ultrasonic anemometer,. capable of monitoring both wind speed and direction. Its main. advantage is that using the ultrasonic technique it has no moving. parts, allowing for the utilization in a variety of applications. requiring low maintenance and fast response to rapid wind gusts.. Wind speed measurement for power turbine control can be. considered as a reference application of it. The proposed. instrument presents a simple design and is constructed using. commercially available components, to reduce development costs.. In the paper the proposed architecture is presented, discussing. the algorithm applied to process the transduced ultrasonic. signals. Some results obtained during the first tests are also. presented and discussed, suggesting for successive improvements.\""
