Hall effect sensors are devices that detect the presence of a magnetic field. They operate based on the Hall effect, which is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor, and a magnetic field perpendicular to the current. Hall Effect Sensors are extensively used in various fields, this post will discuss working, types, applications, advantages, & disadvantages.
