IoT-Based Real-Time Induction Motor Vibration Monitoring System

Abstract

This paper proposes an IoT-based real-time induction motor vibration monitoring system. Vibration is one of the critical parameters that play a critical role in the predictive maintenance of rotating machinery. Due to their complexity and high cost, many current vibration monitoring systems are unsuitable for practical use in small industrial plants. This paper presents a system for real-time vibration monitoring for small rotating machinery operated by an induction motor based on IoT technology. The proposed system consists of an ESP32 microcontroller and an ADXL345 triaxial accelerometer to measure vibration and use it to calculate the vibration velocity. The computed vibration velocity is sent to the Blynk dashboard via Wi-Fi for real-time monitoring of vibration velocity using a gauge and chart. Furthermore, the 4 LED status indicators based on ISO 10816 standards allow users to assess vibration severity and take preventive maintenance actions quickly. In addition, the proposed system adds an auto-calibration function for compensation for static background vibrations, improving measurement accuracy. The proposed system offers a cost-effective, easily deployable alternative for machine health monitoring in small-scale industrial environments.
