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 ...
Most proximity sensors use an electromagnetic field to sense the presence of a target metal. But there are times when it's necessary to sense nonmetallic materials such as plastics, liquids, or ...
Capacitive sensing offers developers a new way to interact with users that overcome the traditional problems associated with mechanical levels or push button switches that engage a solenoid controlled ...
