Modular Anemometric Station for Wind Measurement Using Vortex Whistles and Active Noise Cancellation

Accurate measurement of wind speed and direction is crucial in various environmental and energy applications. The first factor affecting mechanical anemometers with moving parts is the need for frequent maintenance, as they are located in an external environment where dust and moisture obstruct the free movement of the components. However, there are anemometers without moving parts, such as laser Doppler or ultrasonic types; however, their high cost is a significant limitation for taking readings in remote and resource-limited areas. Therefore, this work proposes a new approach by using static elements that produce audible sounds, which can be captured and converted into electrical signals using low-cost acoustic transducers, and through processing, obtain the present wind speed. Likewise, this system includes an omnidirectional design that allows for the replacement of a weather vane to determine wind direction. Additionally, along with environmental sensors, the most important climatological factors in the area are better obtained. Finally, thanks to the modular design, it is possible to implement various flow measurement configurations, allowing for the selection of the best alternative according to user requirements, presenting itself as an economical and ideal solution for sustainable use in remote areas.
