The SmartSense2X_EMC User Module is a SmartSense algorithm on top of the dual-channel CapSense® CSD2X User Module. The SmartSense2X_EMC User Module implements CapSense capacitive sensing. CapSense is a human interface technology that operates by detecting the capacitance of the human body. This is done using sensors that consist of a conductive surface, usually a pad etched on the PCB. Because CapSense detects body capacitance, it can sense through insulating layers such as plastic or glass overlays. These overlays usually constitute the external enclosure of the device. These attributes make CapSense an attractive alternative to mechanical input devices such as push buttons and potentiometers.
