This paper describes a three-week long project for teaching microcomputer-based data acquisition. The project is part of a senior level laboratory course for mechanical engineering students at Santa Clara University. The subject of investigation is the lift coefficient of an airfoil.
Students in groups of two carried out the project in three phases. The laboratory activities in each phase are designed to provide the students hands-on experience with the basic functions, hardware and software of a microcomputer-based data acquisition system. Typical results obtained by the students are presented. The project has been proved to be successful for the students to learn and practice the three basic concepts in data acquisition which are measurements, controls and programming.
