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 ...

This application note describes briefly important factors for the usage of the PCF8883 and PCA8886 sensor devices. Sensor devices, or capacitive proximity switches in particular, is always a ...

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 ...

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 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 ...

The new CA18CB..IO and CA30CB..IO capacitive sensors with IO-Link communication offer exceptional sensing performance and simplified adjustments through their integrated LED bar, which displays on/off ...

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 ...

In this Product How-To article, Riaan du Toit of Azoteq, describes how to use the company’s patented proximity sensing technology to measure and adapt capacitive sensors in wireless mobile devices ...

[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 ...

A device that senses when another object is close by. In a mobile phone, a proximity sensor is most commonly used to detect when the phone is held to the face. Specifically, the sensor detects human ...
