Hall effect sensors, based on a magnetic phenomena, are one of the most commonly used sensing technologies today. In the 1970's it became possible to build Hall effect sensors on integrated circuits with onboard signal processing circuitry, vastly reducing the cost and enabling widespread practical use. One of the first major applications was in computer keyboards, replacing mechanical contacts.
