Hall effect sensors theory and applications

Without sensors most electronic applications would not existsensors perform a vital function, namely providing an interface to the real world. Hall effect sensors, based on a magnetic phenomena, are one of the most commonly used sensing technologies today. In the 1970s it became possible to build Ha...
