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 ...
In Part 1 of this article, we explained popular liquid-level sensing methods and their limitations. We also delved into why capacitive-sensing techniques are superior to traditional methods used for ...
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 ...
