SENSOR, SENSING METHOD THEREOF, AND FILTER THEREFOR

摘要

The present invention discloses a sensor, a sensing method thereof, and a filter therefor. The sensor comprises a sensed-data output unit and a determination unit. The sensed-data output unit outputs sensed data that varies depending on whether or not an object touches or approaches the sensor. The determination unit: compares a threshold value with the sensed data to recognize whether or not the object touches or approaches the sensor; varies first and second strength values using the sensed data; varies the threshold value using the first and second strength values; and outputs an output signal that represents whether or not the object touches or approaches the sensor. The first strength value shows a sensed data value when the object does not touch or approach the sensor, and the second strength value shows the sensed data value when the object touches or approaches the sensor.
