ABSTRACT
Structural Health Monitoring (SHM) programs play a critical role in civil engineering, particularly for evaluating safety conditions and forecasting the strength of large structures such as bridges. Therefore, employing low-cost sensors with implementing different techniques to improve their accuracy compared to high-cost accurate sensors has attracted much attention for structural assessments. In fact, with adequate code and the proper mode to utilize their features and potentials, there is a probability of acquiring valuable data from these low-cost sensors, which can provide helpful insight for the SHM systems. Hence, this study proposes the use of a low-cost circuit for angular measurements based on the fusion of an accelerometer, a gyroscope, and a magnetometer sensor with an Arduino board. In this study, firstly, an introduction through Arduino due and the used sensor is presented. Then angular data acquisition problems, as well as their respective solutions, are presented.
