Low cost multichannel expandable data logger

The design, implementation and testing of a data logger adaptable to different situations field measurement is presented incorporating wireless communication capability and networking devices employing non-volatile mass storage of high speed and high capacity together with new high-performance microcontrollers acquisition units and data logging, remotely operable structured. With a focus on centralized operation in PC application capable of managing the network of recorders and receive stored readings for further processing and presentation of results it is defined. Finally with three units assembled in a real situation of measuring and recording vibrations overlooking a measurement application in structures subject to vibration.
