Liquid-level sensing is used in consumer electronics appliances like washing machines to detect the detergent level. The sensor technolo­gy has progressed to such an extent that refrigerators can now ...
Capacitive sensing is a contactless-sensing technique with numerous applications, ranging from proximity sensing (Fig. 1), gesture recognition, automotive rain sensors, and remote liquid-level sensing ...
Liquid-level sensing based on capacitive sensors comes with its own challenges. It’s like absolute capacitance sensing. Unlike touch detection, the absolute value of the liquid level needs to be ...
The CAP-100 Series capacitive liquid-level sensors provide accurate level sensing through the walls of plastic, glass, and fiberglass bottles. The sensors are suitable for medical applications such as ...
