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 ...

In Part I of this series, we explored the differences between user interfaces based on mechanical buttons and those utilizing capacitive touch sensors. In Step 1 we discussed the look and feel of a ...

As discussed in the first part of the article, the accuracy with which sensor capacitance can be measured using absolute capacitance measurement has a significant dependency on the accuracy of the ...

Tick tracer. Glow meter. Sniffer. They go by many names, but capacitive voltage sensors are all designed to do one thing: detect the presence of voltage in a wire or piece of equipment without ...

Capacitive sensors are found in a wide range of equipment, from consumer electronics to industrial/process control. Touch buttons are increasingly found in lamps and dimmers. Motion detectors can ...
