Design and Development of a 5-Channel Arduino-Based Data Acquisition System (ABDAS) for Experimental Aerodynamics...

Area of Science:

• Aerodynamics
• Instrumentation
• Measurement Systems

Background:

• Aerodynamics laboratories require reliable and cost-effective data acquisition systems.
• Existing systems can be expensive, limiting accessibility for research and education.
• Accurate wind speed measurement is crucial for aerodynamic studies.

Purpose of the Study:

• To develop a new, low-cost Arduino-Based Data Acquisition System (ABDAS).
• To validate the accuracy and reliability of the developed ABDAS.
• To compare two cup anemometer frequency determination procedures using the ABDAS.

Main Methods:

• Development of a simple and reliable Arduino-Based Data Acquisition System (ABDAS).
• Accuracy validation through direct comparison with National Instruments hardware.
• Calibration and testing at the IDR/UPM Institute accredited calibration system.
• Analysis of cup anemometer frequency determination using pulse counting and Fourier transform methods.

Main Results:

• The ABDAS demonstrated simple and reliable design.
• The system's accuracy was confirmed by comparison with commercial high-accuracy hardware.
• Measurements using ABDAS facilitated the analysis of two anemometer procedures.
• The pulse counting procedure yielded a more accurate transfer function for cup anemometers compared to the Fourier transform.

Conclusions:

• The developed Arduino-Based Data Acquisition System (ABDAS) is a viable, low-cost solution for aerodynamics labs.
• The pulse counting method is recommended for more accurate cup anemometer frequency determination.
• This research provides a foundation for accessible aerodynamic data acquisition and analysis.
