Antoniuk, KaterynaPecho, Pavol2025-10-162025978-80-554-2158-2https://drepo.uniza.sk/handle/hdluniza/1297The article focuses on the design and implementation of a system for measuring selected quantities intended for application in a wind tunnel. The theoretical part includes a detailed description of the development of a mechanical transmission system, whose task is to convert aerodynamic forces into an analog signal, which can be measured and processed using Arduino microcomputers. Another part of the work involves the development of software that subsequently processes the analog signal and converts it into a digital format. The result of this conversion is the final display of the necessary data on an external screen in the form of numbers and graphs. Significant attention is given to the calibration of scales and the correct integration of sensors for measuring flow speed, to enhance the accuracy and reliability of measuring the aerodynamic characteristics of tested objects. The output presents a functional prototype of the system and its demonstration on specific examples. The system is expected to be further used for research projects.otherWind tunnelArduinoMicrocomputerSensorLiftDragWorking Paperhttps://doi.org/10.26552/pas.Z.2025.1.38
