The Development of Car Tracking System for Car Sharing Business by Using OBD-II Port

In the last few years, the car rental businesses around the world are greatly growing. Nowadays, the main problems in renting cars are uncomfortably contracting and inconvenient tracking statuses of cars. In order to tracking cars, we need a system which receives raw data from cars and send them to cloud server real-time. Simultaneously, internet of thing technology is implemented to many industries like medical areas, agriculture and intelligent transportation. Hence, the car sharing business can be excelled by merging IOT technology with a traditional methodology. CoBox is an IOT device which designed to accomplish the tracking system. It can receive and transmit data to cars by connecting with OBD-II port. Monitoring, receiving locations from GPS module, managing power supply and connecting to Firebase server are controlled by using ESP32. With these abilities, the car tracking system can collect needed data and can control lock-unlock door real-time.
