Development of Seismic Data Acquisition Based on MEMS Accelerometer MMA7361L

摘要

MEMS Accelerometer MMA7361L is an accelerometer-based sensor has been to develop for seismic acquisition system. The MMA7361L sensor has a linear frequency response to acceleration from 0Hz to 800Hz and works in three components. The signal response test has been done by the MMA7361L sensor compared with the L4C and SM-24 geophone-based sensors in the Laboratory of Volcanology and Geothermal, Cangar, Batu with providing vibrations at varying distances to get a signal response and frequency range of MMA7361L. The test results obtained MMA7361L sensor frequency range from 20Hz until 60Hz in three components work. Therefore, the MMA7361L sensor on this seismic data acquisition system has very low sensitivity.
