Design of an IoT-based Vehicle State Monitoring System Using Raspberry Pi

In this paper, an IoT-based vehicle monitoring system is designed and implemented. The proposed design is comprised of three components: an OBD scan tool, a Raspberry Pi and a Cloud monitoring application. The OBD scan tool collects vehicle information from the OBD-II port of the vehicle, and the Raspberry Pi uploads them onto a cloud server using cellular internet connection. The on-line data as well as the historical data stored on a Cloud server are then accessed by the monitoring application. The application can report data both graphically and descriptively. An algorithm is also proposed to detect faults in engine and cooling systems.
