Method of sensing sliding by hall sensor and sensing system using the same

摘要

A method of sensing a sliding by a sensor including grouping one or more Hall elements into one or more groups, measuring magnetic field strength generated by a magnetic field source, and comparing the magnetic field strength at the one or more Hall elements to determine whether a horizontal sliding occurs.

1. A method of sensing, by a sensor, a movement in a first direction, comprising:
arranging a first Hall element displaced in the first direction from a second Hall element; arranging a magnetic field source configured to generate a magnetic field; measuring the magnetic field at each of the first and second Hall elements; and comparing a strength of the magnetic field measured at the first Hall element to a strength of the magnetic field measured at the second Hall element; and determining whether the movement occurs, wherein the arranging of the first and the second Hall elements comprises arranging the first and second Hall elements on a first body, wherein the arranging of the magnetic field source comprises arranging the magnetic field source on a second body, wherein the determining whether the movement occurs comprises determining whether the second body moves in the first direction relative to the first body, and wherein the first body comprises a terminal comprising a sensor chip.
