The Hall sensor output is weird. First, I use 5V power supply connected to the Hall sensor power cable. Then, the outputs give me three high levels. Whatever how I rotate the motor, the output does not change at all. Then I connect the hall sensor to the controller with the motor when I bought it. The hall sensor does work. What may cause this problem? Has anyone encountered this problem before? How to solve it?

    \$\begingroup\$ Your question is remarkably short on details. Eg. part numbers, how you're driving the hall sensor, the geometry &c. It would help to add those. However if I had to guess what your problem was, it's that your hall effect sensor is only sensitive to one polarity of magnetic field. Try turning it (physically) around, or using the other pole of your magnet. \$\endgroup\$ – james Jan 26 at 20:09
