NXP PCF8883 sensor
User Manual
The integrated circuit PCF8883 is a capacitive touch and 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. conductive foil) can be connected directly to the IC1 or remotely using a coaxial cable.
