The three-component digital seismic exploration geophone is characterized by that three MEMS acceleration sensors are arranged according to the direction in which X-axis, Y-axis and Z-axis are mutually perpendicular, their signal outputs are connected with three 24-bits A/D covnerters, then passed through the chip microprocessor with CAN bus so as to can directly output the digitized seismic signal with good low-frequency resposivity and high vector fidelity.
