WebFeb 2, 2024 · A Hall Effect sensor consists of a flat plate conductor that is used to measure magnetic strength. The sensor can detect when a magnet comes into proximity of the sensor, relaying the information back to a controller. When the magnet is near the sensor, the charge across the plate is pushed to one side, creating a positive charge on one side ... WebDec 22, 2024 · The Hall-effect sensor is a transducer that responds to changes in its output voltage when placed in a magnetic field. The Hall Effect occurs when the action of a magnetic field causes a current in a conductor to deviate from its path. The greater the magnetic field greater will be the sensor output or voltage deviation.
