Abstract Traditional vibration meters are often expensive, limiting their accessibility. This study proposed the design and development of a portable vibration meter that can be implemented at low cost using MEMS accelerometers (ADXL345) and an ESP32 microcontroller. To monitor vibrations, Class I small machines are used. The main aims were to design, develop, test the accuracy, and determine the significant difference in the Velocity and acceleration between the designed portable vibration meter and the commercial vibration meter. When laboratory-testing induction motors with a horsepower range of 0.25-1.0, each motor was measured using both a designed portable vibration meter and a commercial vibration meter; an experimental arrangement was employed to gather data. Evaluation of the results by means of a paired t-test revealed that there was no significant difference in vibration readings between the designed portable vibration meter and the commercial vibration meter in a 0.25 HP induction motor. However, when induction motors were rated higher than 1.0 HP, the results from the designed portable vibration meter differed significantly from those of the reference vibration meter in acceleration data. The study demonstrated that the designed portable vibration meter was comparable to a commercial vibration meter for a 0.25 HP induction motor. However, calibration is necessary to enhance the performance of the designed vibration meter for high-rated machinery, which can help small businesses monitor their machine health and reduce maintenance costs.
