A sensor using a hall sensor to measure the slope using the field alternation amount of magnetic is provided to have the excellent durability and accurately measure the slope regardless of the external environment. A sensor using a hall sensor to measure the slope using the field alternation amount of magnetic comprises: A magnetic(10) having N pole and S pole; a supporting shaft(11) connected to a central part of a magnetic; a center weight(12) preventing the rotation and vibration of the supporting shaft; and a hall sensor detecting the change amount of the electric field according to the N pole and S pole location of the magnetic, in order to calculate the slope. The hall sensor is consisting of: a substrate in which a plurality of magnetoelectric transducers used as a sensing member is integrated; a base in which the substrate is mounted; a hall magnetic field detector(21) detecting N or S pole location of the magnetic; microprocessor(22) computing the slope according to an electric field detection signal outputted from the hall magnetic field detector, and outputting as a digital signal; and an interface outputting the signal outputted from the microprocessor to an external device.
