This paper introduces the self-generation vibration sensor using levitated magnet. We have verified experimentally and theoretically that this sensor is available in frequency of 5 to 25 Hz. The frequency response of sensitivity shows the maximal value at certain frequency. These sensitivities obtained 3.9 V/G at 11 Hz for levitated magnet of neodymium and 3.0 V/G at 10 Hz for the magnet of samarium-cobalt, respectively.
