This study aimed to develop a portable spirometer as a practical learning medium for medical instrumentation education among D3 Radiology students. The development process integrated an MPX5500DP pressure sensor, Arduino Uno microcontroller, and Nextion display to acquire respiratory pressure, process signals, calculate FVC and FEV₁, and visualize spirograms. The implementation was conducted through prototype development and technical testing using 1-L and 3-L calibration syringes, with five repeated measurements for each reference volume. The activity was carried out during the instrument development and laboratory testing phase. The resulting prototype integrated sensing, data acquisition, signal processing, parameter calculation, and visualization in a portable system. The device is expected to support practice-based learning and improve students’ understanding of medical instrumentation principles
