As deficiencies and inherent defects of ordinary magnetoelectric velocity sensor in the detection of seismic sig-nals,a mechanism of ultra-low-frequency absolute vibration detection based on magnetic damping is proposed. The low-frequen-cy seismic signals were detected by means of microcontroller as the core,combination of hardware and software,intelligent data processing. It has a certain practical value in earthquake detection and early warning.
