Workers in the aerospace manufacturing industry use handheld powered tools in their work processes, exposing themselves to vibration transmitted from the tools, known as hand-arm vibration. Regular and frequent exposure to this occupational hazard can negatively impact workers’ health and well-being. Therefore, this study aims to address this concern through the development of an Arduino-based triaxial accelerometer system to acquire vibration acceleration. The study involved three phases: designing a schematic diagram, developing the circuit, and conducting an experimental task. The developed Arduino-based triaxial accelerometer system effectively captured and recorded the vibration levels. The vibration levels measured by the Arduino-based system ranged from 0.69 m/s2 to 1.21 m/s2, while those measured using the accelerometer ranged from 0.87 m/s2 to 1.51 m/s2, respectively. The experimental task was conducted at different task times, and the analysis performed shows a relationship between vibration levels and task times. Thus, the study validates the effectiveness of the Arduino-based system as a low-cost option for real-time vibration monitoring, emphasizing the need for such monitoring to prevent hand-arm vibration syndrome.
