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 sensors work by detecting the change of capacitance introduced by the finger touching near the electrode. Such change is so small that detecting it unambiguously is challenging, and has ...

Capacitive sensors are typically cost-effective and deliver low-power performance features aligned with today’s trends for consumer and industrial applications. Capacitive sensors are cost effective ...

Capacitive touch sensors are entirely in the domain of DIY, requiring little more than a carefully-chosen conductive surface and a microcontroller. This led [John Phillips] to ask why not embed such ...

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 ...

Capacitive sensors supply high accuracy at a relatively low cost. But system designers attempting to use them have been forced to first convert the capacitance to a voltage, then convert the voltage ...

This paper describes the design and characterisation of a long-range capacitive displacement sensor, NanoSensor® model NXE2. Special emphasis is placed on the design features and metrological ...

Non-contact displacement measurements can be made rapidly and with high precision using capacitive sensors over a modest range. The main features are: Capacitive sensing is a non-contact measurement ...

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 ...

Engineers developing heavy equipment such as tractors, cranes, wood chippers, and construction equipment need to include incline sensors and indicators—both to ensure that workers do not operate the ...
