Cost-Effective Accelerometer Integration for Vibration Monitoring
摘要
Vibration data is essential across industries with wireless connectivity which provides invaluable insight into essential statistics, be it for Predictive Maintenance (PdM) for factory machinery, Structural Health Monitoring (SHM) of civil infrastructure, or for detecting Customer Flow in Retail Analytics and helmet impact alert system. The primary objective of this project was to develop an ultra-low-cost solution for revolutionizing vibration monitoring at immense scales. The novelty of this project lies in creating a solution that offers the highest data acquisition rate performance under an arbitrary cost ceiling of Rs. 1000 that can be cost-effective technology when implemented in, along with the previous scenarios, Consumer Appliances and other applications demanding tremendous volume but which are limited by cost. The keystone of our methodology centers on the consistent logging of data that can be effectively utilized to improve designs. The hardware configuration includes connecting an ESP32 microcontroller to a TCA9548 multiplexer and two ADXL345 sensors where the multiplexer can switch between sensors in nanoseconds to get a higher data rate. The whole system uses I2C protocol for data transfer.
