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 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 ...

Ken-ichi Nomura (Researcher) and Hirobumi Ushijima (Leader, also Deputy Director of the research center), the Advanced Surface Processing Team, the Flexible Electronics Research Center (FLEC; Director ...

Now that we have discussed the theory about the sigma-delta modulator, let us design a simple proximity sensor that will detect an approaching hand and switch on an LED. A 0.5 mm 2 wire, 10 cm long, ...

CARLO GAVAZZI is proud to announce the launch of the new CD34 Series liquid level capacitive sensors. The CD34 Series is designed to detect water-based liquids through non-metallic walls, i.e. plastic ...

Carlo Gavazzi is excited to introduce three new series of M12 Capacitive Sensors with IO-Link Communications. Based on our 4th generation TRIPLESHIELDTM sensors, these CA12 Series Sensors represent ...

Proximity sensors detect objects without physical contact. Most proximity sensors emit an electromagnetic field or beam and look for changes in the field. The object being sensed is called a target.

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. The ...

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 ...

One of the backbones to the success of any automated process is the accuracy to which one can detect and measure the various elements involved. Whether the process requires precise measurement and ...

Capacitive displacement sensors span a wide range of resolution, from the touchscreen sensors which can only detect displacement as a binary state, all the way to the sensors in semiconductor fabs ...
