Abstract

Vibration is a nature effect of machine or a compressor that operate with movement.Therefore,if the machine is work unproperly,the vibration that generate form the machine will be different with the vibration that generate when it is operate under normal condition.If this early signal didn’t detect by the people who operate these machine,it may cause a major accident such as explosion.Therefore,these machines have to be monitor and require maintenance from time to time.This project aims to design and build a self-powered wireless sensor node for monitoring the vibration level of a single artificial source.The sensor node is a piezoelectric cantilever that is self-powered.It was going through a simple test in laboratory to characterise its properties.Hence,when the piezoelectric cantilever harvests enough energy from the vibration source,it is able to power up transmitter to transmit pulses to trigger a receiver node that placed from a distance away.All the data is collected and send via IoT.Hence,when the vibration level reaches the resonance frequency of piezoelectric cantilever,a pulse was send to the person who is monitoring the vibration level of the source.Besides that,IoT is implemented in this project in order to enable the data received to be access to network database for wide range monitoring.
