Hall sensor
Hello! I have a Hall sensor here and I am trying to make it work with alternating current. The problem is that the output voltage (i.e voltage difference between the two terminals of the sensor) is not sinusoid! It is something like white noise. When you approach a magnet there is some peak visible in the FFT in the desired frequency ok. But its still burried into noise. Shouldnt the output be sinusoid on its own even without a magnet?
Any readings on Hall sensors would be appreciated too. Thanks!
