[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.

Q: Is this a relatively new form of non-contact proximity sensing? A: Actually, it’s the oldest. As soon as photosensitive and photoconductive sensors, along with basic electrical components, were ...

We propose a method for simultaneous articulated robot posture estimation and environmental mapping by integrating data from proximity sensors distributed over the whole body. Our method extends the ...

Nobu Teranishi, Albert Theuwissen and Eric Fossum, who between them made key breakthroughs in the development of both CCD and CMOS sensors, have collaborated on an article for the open-access "Annual ...

In this modern age, IR sensors are typically used in motion detectors and the best VR headsets. In the latter, they measure the depth of a space and your proximity to things in your environment.

The ProX 950 production printers offer, thanks to the stereolithography (SLA) system, the highest accuracy, speed and the largest format available on the market today. These printers offer ...

If you're looking for more control over how your keys feel and sound, you'll want to turn to one of the best hot-swappable keyboards. These decks allow you to easily remove and replace the ...

Humidity sensors are essential to regulating many indoor and industrial environments. Fang Liu, Jin Hon, and colleagues develop a humidity sensor using graphene oxide quantum dots (GOQDs ...

Sensors are devices that detect and quantify physical aspects of the world around us. The measurement can either be read directly or converted to a signal for processing by electrical, hydraulic ...

CES 2025 showcased advances in power and size savings, from energy-harvesting solutions to tiny sensors for wearables and highly integrated wireless SoCs. Sustainability was on full display at CES ...

Sensify is a new technology that can turn Zigbee switches, bulbs, and plugs into sensors with a firmware update. This could be how Philips Hue will bring ambient sensing to its smart lights.
