Working Principles

CY8CMBR3110-SX2IT utilizes capacitive sensing technology to detect changes in capacitance caused by the presence or absence of a conductive object (such as a finger) near the touch sensing inputs. This change in capacitance is then converted into digital signals, which are processed to determine touch events or gestures.

The controller operates by periodically scanning the touch sensing inputs and comparing the measured capacitance values against predefined thresholds. When a touch or gesture is detected, the controller generates corresponding output signals or interrupts.
