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 ...

Capacitive sensors are typically cost-effective and deliver low-power performance features aligned with today’s trends for consumer and industrial applications. Capacitive sensors are cost effective ...

NEWARK, DEL, Feb. 26, 2025 (GLOBE NEWSWIRE) -- The global capacitive sensor market is poised for significant expansion, with sales projected to rise at a steady compound annual growth rate (CAGR) of 6 ...

Depending upon the distance between the surface of a capacitance probe and a target source, the electrical capacitance that is formed between these two objects will vary. In an effort to improve ...

Capacitive touch sensors are entirely in the domain of DIY, requiring little more than a carefully-chosen conductive surface and a microcontroller. This led [John Phillips] to ask why not embed such ...

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 ...

If you’re the person tasked with controlling the level of fly ash in collection hoppers, you know how difficult the application can be. What at first looks like a simple measurement quickly proves to ...

Capacitive sensors supply high accuracy at a relatively low cost. But system designers attempting to use them have been forced to first convert the capacitance to a voltage, then convert the voltage ...

If you’ve got a smart home, or you just want to know how soaked your garden is getting in the winter, you might want to measure rainfall. There are a bunch of ways to go about it, and this capacitive ...
