General Description

The integrated circuit PCF8883 is a capacitive proximity switch that uses a patented (EDISEN) digital method to detect a change in capacitance on a remote sensing plate.

Changes in the static capacitance (as opposed to dynamic capacitance changes) are automatically compensated using continuous auto-calibration.

Remote sensing plates (e.g.
