Abstract:This paper introduces a seismic intensity meter design based on memsaccelerometer,taking the STM32F107 as the sampling and data processing core,three axis mems accelerometer LIS344ALH detected acceleration changes,ADS1248 sampled the high precision 24 bit.Filtering three axis acceleration data,selecting effective peak ground acceleration(PGA),seismic intensity is calculated.The test shows that the performance parameters of seismic intensity meter fully achieve the desired design requirements.
