Has been made a vibration sensor using electrolyte that tested by using the vibrating table.This vibrating table had been calibrating with the sensor geophone. The research was conducting to determined the signal response of the vibrating electrolyte sensor by utilized of CuSO4 solution. Output of the sensor signal were still very small, so need to be strengthened by 355 times (51 dB). The type of output sensor from the amplifier was sinusoidal type and recorded by the digital oscilloscope. The testing was doing by simulating sensor vibration table that actived with frequency variation. Geofon sensor response amplitude as a comparator had a natural frequency of 17 Hz and a bit of sensitivity to vibration by 34 V/ms-1, while the electrolyte sensor had a flat amplitude response of the frequency of 0.5 Hz up to 27.7 Hz and a sensitivity to vibration by 19 mV/ms-1.
