The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

A new technology has been developed that enables cuffless non-invasive blood pressure monitoring by using ultrasonic to track real-time changes in vascular diameter-without the need for a traditional ...

I tried a techy new knife at CES 2026. Here's my take on whether this pricey blade is worthy of the hype. David lives in Brooklyn where he's spent more than a decade covering all things edible, ...

Aqara has announced the Spatial Multi-Sensor FP400, a new presence sensor that it says is precise enough to suss out whether you’re sitting, standing, or lying down. The FP400 builds on several past ...

You brush your teeth, floss regularly and faithfully wear your retainer every night. But despite your diligent oral health habits, your retainer or mouth guard can get yellowed, cloudy or stained.

MIT researchers have found a way to use the mechanical vibrations of sound waves to shake water molecules free from a storage medium. The breakthrough significantly speeds up the process of harvesting ...

Pic Microcontroller Garage Door System Ultrasonic Sensor is a hands-on course focused on practical PIC Microcontroller development. This repository contains curated starter code, wiring notes, and a ...

Ultrasonic sensors measure the distance between a target and the sensor using high-frequency sound waves that are inaudible to humans. The process is simple: the sensor emits ultrasonic waves, which ...

As robots increasingly enter human spaces, robotics companies will need to think about safety differently than they did when robots were largely siloed from their human counterparts. Sonair thinks its ...

Jennifer’s garage hasn’t been working for two weeks, so we got to her as soon as we could. We realized pretty quickly it was the child safety sensors on the floor! If you have a project you’d like ...
