Capacitive sensing libraries for the Arduino and just about every other microcontroller platform have been around for ages now, but if you’d like to put a slightly complex cap sense pad in a PCB ...

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, ...

Howard A. Schaevitz Technologies Inc. Pennsauken, N.J. Engineers continue to increase their use of linear-position and displacement sensors for providing real-time information to feedback-hungry PLCs ...

In the last Sensor Sense we looked at capacitive touch switches used for on/off control. But these switches are also found in capacitive touch sliders that can control various levels, such as volume ...

The sensors can be utilized as encoders because they offer the performance and reliability needed for dynamic closed-loop control. They provide continuous, precise position feedback that permits ...

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 ...

Last year, Automation World examined the differences between accuracy, resolution, and precision in the encoder world. And while understanding the differences among these terms is important to ...

Many billions of mechanical buttons in cell phones, cars audio systems, notebooks, PCs, white goods, and industrial applications have been replaced with capacitive sensing buttons. The use of ...
