PURPOSE: A vibration sensor using a hall effect is provided to obtain an electric potential difference without forcefully applying current to a metal plate. CONSTITUTION: A vibration sensor using a hall effect comprises a vibration sensor mount(100), a spring(110), a metal plate(120) and a magnet(130). A space is formed in inside of the vibration sensor mount. The spring is installed to across faced two pages of the vibration sensor mount inside. The metal plate locates in the center end of the spring. The magnet is installed on the one side of the vibration sensor mount inside in order to be separated from the metal plate and to be faced with the metal plate. The one part of the metal plate surface is formed to be added to gold or silver. The rest part of the metal plate surface is formed to be added to aluminum.
