A real-time bridge structural health monitoring device using cost-effective one-axis accelerometers

This work demonstrates a real-time bridge structure health monitoring device (HMD) with using three 1-axis accelerometers, Gateway, and analog to digital converter (ADC). The proposed HMD achieves the features of low cost and data synchronization of three 1-axis accelerometers. Furthermore, we develop a packet acquisition program to receive the data from remote sensors and then classify it based on time and date. Compared with 3-axis accelerometer, our proposed 1-axis accelerometers based device achieves 59.59% cost saving with high sensitivity 2000 mV/g.
