Creating capacitive touch-sensitive buttons is easy these days; many microcontrollers have cap-sense hardware built-in. This will work for simple on/off control, but what if you want a linear, ...

Capacitive displacement sensors turn tiny gaps into actionable signals. By measuring changes in capacitance as target moves, these devices deliver precise, non-contact readings of position and motion.

Depending upon the distance between the surface of a capacitance probe and a target source, the electrical capacitance that is formed between these two objects will vary. In an effort to improve ...
