Traditional wireless sensor networks work with scalar data like temperature o humidity because they have strong restrictions on bandwidth and energy consumption. Nevertheless, in recent years, technological advances have permitted a significant growth in the use of these networks for processing and transmitting complex signals like audio, video or vibrations. This work reports the development of an adaptable platform for sensor nodes, which are able to measure, process, store and wirelessly transmit diverse physical variables. The design of these nodes allows the adaptation of them for the use in applications that require to measure and process signals of varied complexity. In addition, the nodes permit the wireless transmission of the information obtained from the local processing of the signals mentioned above. Finally, the adaptation of the platform to measure vibration in road bridges is described as a case study.
