GH6210 is a 3-channel high-precision smart capacitive sensor applicable to high-sensitivity scenarios including touch and proximity sensing. By leveraging the built-in RF filter circuit, the sensor is highly immune to interference. Each sensing channel can be configured individually. In addition, a low-power data processor is integrated to support differentiated data processing requirements. Integrated with a 16-bit low-power MCU, the sensor supports a rich set of slide and custom gestures.
