Abstract
Provided are a sensing apparatus using a plurality of Hall sensors and an apparatus using the sensing apparatus. The sensing apparatus is configured to measure an intensity of a magnetic field with respect to a magnetic element by using a plurality of Hall sensors and to identify a body that includes the magnetic element.
Claims18
A sensing apparatus, comprising:
- Hall sensors arranged symmetrically to each other;
- and
- a magnetic element disposed at a distance from the Hall sensors and configured to generate a magnetic field, wherein the Hall sensors are configured to sense a magnetic field intensity of the magnetic element.
An apparatus sensing a magnetic field, comprising:
- a first body having sensor groups symmetric to each other;
- and
- a second body having a magnetic element that is attached to the first body,
- wherein the magnetic element generates a magnetic field, and
- wherein each of the sensor groups comprises Hall sensors and detects the magnetic field.
