Hall sensor detection device

The utility model discloses a Hall sensor detection device, which belongs to the technical field of automobile terminal detection, and comprises a support mechanism and a detection mechanism for detection, the top of the support mechanism is rotatably connected with a rotating gear, and the axis of the rotating gear is provided with a connecting mechanism. The connecting mechanism comprises a fixing rod designed in the radial direction of the rotating gear, and a Hall sensor designed to be close to the rotating gear is fixedly installed on the end face, away from the axis, of the fixing rod. The rotating gear and the Hall sensor adjacent to the rotating gear can generate variable waveforms due to the concave-convex surface of the rotating gear in the rotating process, the variable waveforms are displayed on the oscilloscope under the action of the connecting line, and the waveforms are correspondingly changed along with the rotating speed of the rotating handle. Therefore, the Hall sensor does not need to be
