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 ...

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, ...

Innovative capacitive proximity sensors are revolutionizing energy management practices by cutting power consumption in commercial buildings, industrial facilities, and renewable energy installations.

Guest columnist Helen Francis, product marketing manager at Atmel Touch Technology, says that capacitive touch can be used as a proximity sensor In recent years, capacitive touch technology has ...

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 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 ...

A new line of capacitive proximity switches monitors liquids, pastes, and bulk materials — even through nonmetallic dividing walls. The devices can also be used as limit switches, contact-free ...

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 ...

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 ...
