Hall Effect is one of important physical phenomenon in the microelectronic field, the development of Hall Effect device, based on Hall, and has a wide application in industry, transportation and scientific research. During the engineering application research and practical teaching of some related majors, it is very vital to use excellent technique method and means. A kind of experimental device on Hall sensor, developed by the paper, is able to generate the corresponding magnetic field, thus enriching it and making for comprehensive observation of Hall sensor;the output characteristic of Hall sensor can be observed and analyzed more vividly, intuitively and thoroughly through a oscilloscope;easy operation, convenient use and comprehensive observation are focused on this design;it not only provides an effective experiment method and means, but also is beneficial to cultivate pioneer thinking and engineering application ability for students. Of course, it is also an effective experimental development tool in engineering application.
