Simple capacitive proximity/touch sensor problem

WebDec 19, 2024 · Capacitive proximity sensors are contactless sensors that detect both metallic and non-metallic objects, including liquid, powders, and granular. It operates by detecting a change in capacitance. Similarly to inductive sensors, it consists of an oscillator, Schmitt trigger and output switching circuit. WebCapacitive touch sensing is a way of human touch sensing, that requires little or no force to activate. It may be used to sense human touch through more than a quarter of an inch of plastic, wood, ceramic or other insulating material (not any kind of metal though), enabling the sensor to be completely visually concealed.
