What is the principle of operation behind this test instrument ... between these two capacitors in series is critical to understanding how the capacitive voltage sensor works. Let's return to the ...

(This is the “Eddy Current Killed Oscillator,” or ECKO, principle ... applications sometimes affect the inductive sensor performance. Capacitive proximity sensors detect both metallic ...

The iPhone 16 series, for example, uses a similar capacitive sensor for its Camera Control ... Either way, it’s based on the same principle of keeping this secure data on a separate part of ...

[Magnus] pairs the off-the-shelf capacitive sensor with an ESP32 charged with reading it and reporting back to Home Assistant. It’s also outfitted with a heater to keep it at a constant ...

Capacitive sensors are typically made of several layers of materials, often on a circuit board. In touch-screen or button applications, a sensor IC detects not absolute capacitance, but a change in ...

If you’re ever hunting for a touch sensor but can’t get your hands on one, [Alan Chatham’s] tutorial on simple DIY capacitive touch sensors might be just what you need to keep things moving ...
