Abstract
A proximity sensor and a detection method thereof are provided. The proximity sensor includes the proximity sensing unit and a control unit. The proximity sensing unit generates a sensing value in response to an object. The control unit is coupled to the proximity sensing unit. The control unit obtains the sensing value from the proximity sensing unit, compares the sensing value and a default value to obtain a comparing result, calculates a status accumulative time according to the comparing result, and determines whether the status accumulative time exceeds a default time, so as to determine a proximity status of the object.
