Abstract
:A new type of seismic intensity meter based on MEMS accelerometer is introduced. It employs STM32F107 as the data processing core and detects the changes of acceleration with triaxial MEMS LIS344ALH and uses ADS1248 for 24 bit data sampling. The test on vibration table shows that the linearity of the meter is δL = ± 1.4%, and the sensitivity is Kc = 0.9671 V/g with zero deviation of 0.0043 g. The seismic intensity meter has the advantages of simple structure and stable performance and it is appropriate for intensive layout on a large scale.
