In the tunnels of the Metropolitan Expressway, there are 217 jet fans installed, necessitating lane restrictions for many days for inspection purposes. Therefore, our aim was to conduct measurements of jet fan motion to understand structural anomalies and achieve continuous monitoring. In our previous report, we explained that frequency analysis and trajectory analysis using a measurement 3-axis accelerometer are effective for measuring jet fan motion. In this report, we developed a MEMS sensor integrated with low-cost components based on these two analysis methods. We compared the measurement results of the MEMS sensor with those of the measurement 3-axis accelerometer and found them to be equivalent. This verification that the MEMS sensor is effective for measuring jet fan motion.
