Principle of Capacitive Touch and Detection Chips

Capacitive sensing chips work by detecting changes in capacitance caused by the presence of a human body, finger, conductive object, or liquid near the sensing electrode.

Working Principle:

• When a finger or conductive object approaches the sensing pad, the capacitance between the electrode and ground increases.

• The chip detects this variation and determines whether a touch or proximity event has occurred.

• Output is provided via GPIO, I²C, or BCD interface to the host controller.

Key Features:

• Self-calibration to adapt to environmental changes

• Strong anti-interference capability

• Non-contact sensing through non-metallic surfaces (glass/plastic)

• Ultra-low power consumption for battery-powered applications
