The World Solar Challenge is a bi-annual competition that allows universities from around the world to design and build a fully solar-powered vehicle that can travel 3000km across Australia at an average speed of over 60 km/h. In order to monitor the solar car remotely, a data acquisition system with wireless transmission capabilities has to be developed. Various types of sensors are chosen to monitor information such as voltages, currents, temperatures and vehicle speed. All these data will be transferred wirelessly through a radio modem and displayed on a laptop in an escort vehicle following the Solar Car.
