First discovered by Edwin Hall in 1879, the "Hall Effect" is used to detect the presence of a magnetic field by an induced change in the electric field. Modern day silicon-based Hall effect sensors are used for position, speed and acceleration detection, object recognition, index counting and more in a wide range of industrial and automotive applications.
Why are they used:
TI's DRV5000 Hall effect sensors support a variety of applications.
Some examples include:
