In industrial machines, vibration monitoring is a vital instrument to the system, as it can detect the smallest faults at an early stage and thus prevent the breakdown of the machine. This project is about a sensor- based vibration monitoring system that keeps on taking the vibration signals from the machine and comparing them to a predetermined reference signal which is fault-free. If the detected vibration pattern is similar to the reference signal by 90% or more, the machine is considered to be in good condition. Any considerable difference is signifying the abnormal operation or a potential fault. The system employs a vibration sensor and a microcontroller to capture and handle the signals in real time. This easy and efficient way of fault identification, such as the instability, the misalignment, or the bearing wear, which can be the cause of the machine's death. The method, which is also applicable in various industrial settings, could lead to a significant increase in machine reliability and operational safety, besides being a valuable tool for predictive maintenance. Vibration Analysis (VA) is the most significant method utilized in the condition-based maintenance strategy, by a large margin. It offers a straightforward and immediate manner of locating the source of the problem, which is very supportive, particularly in the early stages. The continuous monitoring and the mechanical system's occasional check-up through this instrument is a reliable and efficient way, hence, it is possible to have the very first alert almost for any incident before the situation becomes a serious failure.
