  This paper describes the work that has been done in the design and
development of a wireless OBD II fleet management system. The system aims to
measure speed, distance and fuel consumption of vehicles for tracking and
analysis purposes. An OBD II reader is designed to measure speed and mass air
flow, from which distance and fuel consumption are also computed. This data is
then transmitted via WiFi to a remote server. The system also implements GPS
tracking to determine the location of the vehicle. A database management system
is implemented at the remote server for the storage and management of
transmitted data and a graphical user interface (GUI) is developed for
analysing the transmitted data . Various qualification tests are conducted to
verify the functionality of the system. The results demonstrate that the system
is capable of reading the various parameters, and can successfully process,
transmit and display the readings.
