IoT-based Web-Integrated OBD-II Telematics for Real-Time Vehicle Health Monitoring System

A real-time vehicle health monitoring system remotely collects the operating status of various sub-systems in the vehicle. Vehicle diagnostic data is helpful in driver behavior analytics, vehicle data analytics, and automotive insurance markets. A live vehicle health checking system utilizing Internet of Things (IoT) technology has been proposed and implemented using the ELM327 OBD scan tool and MQTT protocol. The OBD scanner remotely acquires the data of various vehicle parameters while the vehicle is on the move. Then, the MQTT protocol forwards the data from the vehicle to a web application using an HIVEMQ broker. The received diagnostic information is displayed on the webpage using animated gauges. Alternatively, the collected data is compared with the predefined thresholds and alerts the user for any detected faults.
