Smart portable system for monitoring vibration based on the Raspberry Pi microcomputer and the MEMS accelerometer

Abstract

In this work, an internet of things (IoT)sensing and monitoring box has been developed.  The  proposed low-cost system  is  a  portable  device  for  smart buildings  to  measure  vibrations, monitor,  and  control  noise  caused  by  the industrial machines. We will present an instrument and a method to measure the vibration and tilt of a mechanical system (air conditioner). The primary goal is to create a signal acquisition and monitoring system that is both user-friendly and affordable, while also delivering exceptional precision. The key concept  is  centered  around  acquiring  and  processing  signals  through  the RaspberryPi. We will use for the first time as an application, which does not exist before, a conversion method to control and monitor remotely the noise generated  by  the  machines.  Once  the  noise  reaches  a  high  value  or  the  air conditioner  is  too  much  tilted,  the  system  sends  an  alert  in  the  form  of  an email.  We  will  use  the  Python  language  to  acquire  and  process  the  signal and send the alerts. The proposed approach is straightforward to implement, and  the  obtained  results  demonstrate  a  high  level  of  accuracy  that  is consistent with the existing literature.
