How a hall effect device works
WebThese devices have a range of applications, with Hall effect sensors often used in automotive systems to sense position, distance and speed. These clever devices are used in various fields, but perhaps most notably in anti-lock braking systems (ABS), and internal combustion engines to assist with ignition timings. WebHistory of the device. Initial work on Hall effect thrusters was carried out independently in the United States and the Soviet Union in the 1950s and '60s. Because of inefficiency in the early designs, development of this type of thruster came to a halt in the US in about 1970. However, continuing research in the Soviet ...

A Hall effect sensor (or simply Hall sensor) is a type of sensor which detects the presence and magnitude of a magnetic field using the Hall effect. The output voltage of a Hall sensor is directly proportional to the strength of the field. It is named for the American physicist Edwin Hall. Hall sensors are used for proximity sensing, positioning, speed detection, and c… WebThese devices have a range of applications, with Hall effect sensors often used in automotive systems to sense position, distance and speed. These clever devices are used in various fields, but perhaps most notably in anti-lock braking systems (ABS), and internal combustion engines to assist with ignition timings.
WebHall effect devices produce a very low signal level and thus require amplification. ... Hall sensors can detect stray magnetic fields easily, including that of Earth, so they work well as electronic compasses: but this also means that such stray fields can hinder accurate measurements of small magnetic fields.
