Working Principles

CY8CMBR3195-LQXIT utilizes capacitive sensing technology to detect changes in capacitance caused by a user's touch. It employs an array of touch channels connected to electrodes, which form a capacitive field. When a conductive object, such as a finger, approaches or touches the surface, it alters the capacitance at specific touch channels. The controller measures these changes and generates corresponding touch events or proximity detection signals.
