Apple, Garmin, Samsung, Google or Amazfit? I compared each one against a chest strap for heart rate accuracy and found a ...

ST’s VL53L5CX is a very small 8×8 grid ranging sensor that can perform distance measurements at a distance of up to 4 meters. In a recent video,[Henrique Ferrolho] demonstrated that ...

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 ...

This all-purpose presence sensor is a master at monitoring indoor activity and linking it to smart home features you already use. Tyler has worked on, lived with and tested all types of smart home and ...

Have you ever wondered how a robot navigates a cluttered room or how a drone maintains its altitude with pinpoint accuracy? The secret lies in the tools used to measure distance, an often-overlooked ...

Insight on Diodes Inc.’s first automotive-compliant 3D linear Hall-effect sensor. How it allows for reliable and high-precision contactless rotary motion and proximity detection. Application targets ...

iPhone and iPad users are already very familiar with something called “proximity pairing.” First introduced with iOS 11, this feature lets users transfer backup and other data from one device to a new ...

There are a whole bunch of different ways to create 3D scans of objects these days. Researchers at the [UW Graphics Lab] have demonstrated how to use a small, cheap time-of-flight sensor to generate ...

A light source and photosensor combine for effective, reliable, non-contact proximity detection of nearby objects. Part 1 of this article looked at the principles and three basic approaches to optical ...

Understanding acoustic feedback in hearing aids. Power consumption challenges in hearing aids. Functionality integration and its impact on energy consumption. The benefits of using photoreflectors for ...
