I&Q Demodulation Cap Sensing

ams’ I&Q demodulation based capacitive sensors, separate the measured capacitance into the parasitic resistive and capacitive part. Therefore the sensors are ideal for detecting human presence or interaction as well as sensing different liquids and fluid levels. The sensors can be used in various applications.
