The following guide provides a review of the types of proximity sensors for prolonged detection, followed by a look at capacitive sensing design specifically for occupancy-type solutions. A variety of ...

Touch-free user interfaces are the new trend for automotive design engineers. There are multiple ways to implement this feature, and one of them is through proximity sensing. Proximity sensing is a ...

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 ...

Two tiny ICs and a few passive components can yield a capacitive proximity sensor with excellent sensitivity and extremely fast response time. The circuit’s operation leverages the pulse-front-edge ...

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 ...

Capacitive proximity sensors allow sensing of metal and non-metal objects through insulating materials such as wood or plastic and are often used to sense fill levels of liquids or powders. New lower ...

[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 ...

Inductive sensors are non-contact proximity sensors that detect ferrous targets, ideally ones made of mild steel thicker than one millimeter. They consist of four major components: a ferrite core with ...

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 ...
