- Abstract
- A wireless data logging system connected with accelerometer was developed for measuring vibration in harsh environment where conventional vibration equipment could not be used, e.g., on deck of the battleship, surface of the submarine or airplane, etc. To minimize wired connections, the module used a battery to supply power, and the data was recorded by the module itself on the SD card. Data logging was carried out through Arduino. Because the voltage levels of the accelerometers were different, the internal circuits were adjusted by changing the voltage levels through level shifting. Data logging was optimized using the hardware interrupt and double buffering to maintain a constant sampling rate during data logging and to prevent loss of data. The vibration data obtained through the manufactured module was compared with data measured by LMS test to confirm the validity of the signal. It was also confirmed that the module measurement data was normal even during long-time measurements.
