In this work, a network based on wireless sensing modules has been developed to measure strains, temperature and accelerations in multiple points of the vehicle. The obtained data of each sensor is prepared, processed, stored and transmitted in time intervals towards a receiver. The receiver in turn sends the information to an Internet server through GSM cellular technology using the GPRS protocol. In the server, the data is stored and analized as it is received so it can be visualized as close as real time as possible by anyone with access to the Internet.
