Validating a low-cost seismometer using a shaking table

Ambient vibration measurement using a seismometer represent non-invasive and non-destructive method for seismic-related studies. This inhibits widespread applications, i.e., assessing site fundamental frequency, estimating bedrock level, calculating building natural deducing shear wave velocity profile. However, the instrument required to carry out such ambient is generally expensive. Recently, there low-cost Raspberry Shake 3D (RS-3D) available on market. based Pi hardware. It contains three 4.5 Hz orthogonally oriented geophones, which can be set at sampling rate of 100 bandwidth -3dB points 0.6 34 Hz. Thus, laboratory testing was carried assess this device’s performance in demanding application. Generally, RS-3D demonstrates great performance. Further detailed results are presented paper.
