Low-cost wireless sensor node which is capable of collecting synchronous acceleration time history with online data repository.

Advances in wireless sensor networks are well proven and commonly used in structural health monitoring. Structural health monitoring (SHM) using wireless sensor networks (WSN) is the modern paradigm which incorporates automated systems for data acquisition, in monitoring, analysis, and identification of structural responses and defects. Even though currently used WSN are economical compared to tethered monitoring systems, it is still unaffordable. The costly nature of traditional data loggers and the low penetration nature of currently used networking protocols, through civil structures thus requiring dense array of sensors, increase the overall cost of a WSN. This low cost WSN is capable of capturing synchronous acceleration response data with the sampling frequency of 100Hz.
