FDC2212 Capacitance-to-Digital Converter

Capacitive sensing is a low-power, low-cost, highresolution contactless sensing technique that can be applied to a variety of applications ranging from proximity detection and gesture recognition to remote liquid level sensing. The sensor in a capacitive sensing system is any metal or conductor, all.
