Hall sensor characteristic measurement experiment device

The utility model discloses a Hall sensor characteristic measurement experiment device. The device comprises a displacement giving device, a Hall sensor, an amplification circuit, an A/D conversion circuit and a microprocessor. The displacement giving device is connected with the Hall sensor, the amplifying circuit, the A/D conversion circuit and the microprocessor in sequence; the displacement giving device gives out displacement changes, and the Hall sensor senses displacement change signals, carries out amplification and A/D conversion on the displacement change signals in sequence and thensends the displacement change signals to the microprocessor to be processed. The Hall sensor characteristic measurement experiment device provided by the utility model can automatically record and process data, does not need to manually record and process experiment data, and is high in experiment efficiency. Besides, in the experiment process, measurement signals needed by an experiment are automatically given through t
