IoT-Based Real-Time Monitoring System for Propeller Shaft in Vehicles Using ESP8266

The propeller shaft is an essential component in vehicles that transmits power from the engine to the differential and wheels. Failure of the propeller shaft due to excessive vibration, overheating, or abnormal rotational speed can lead to severe mechanical damage and safety issues. Traditional inspection methods are mostly manual and cannot provide continuous monitoring of the shaft condition. This research presents a real-time monitoring system for vehicle propeller shafts using IoT technology. The system employs sensors to monitor temperature, vibration, and rotational speed of the shaft. These sensors are interfaced with an ESP8266 NodeMCU microcontroller which processes the data and transmits it wirelessly through Wi-Fi to the Blynk IoT platform. The data can be monitored remotely using a smartphone application, allowing users to observe shaft conditions in real time. The proposed system also provides fault detection by identifying abnormal values in temperature, vibration, and speed. The developed system is cost-effective, reliable, and suitable for preventive maintenance in automotive systems.
