A magnetometer is a device that measures magnetism: the direction, strength, or relative change of a magnetic field at a ...

A compact embedded systems project that uses a Heltec Wireless Stick V3 (ESP32‑S3) and a pair of IR break‑beam sensors to detect direction and count people moving through a doorway. The device can run ...

Here’s a fun build from [RootSaid] that is suitable for people just getting started with microcontrollers and robotics — an Arduino-controlled two-wheeled robot. The video assumes you already have one ...

Abstract: This document presents a CMOS image sensor (CIS) with a high-speed single slope ADC(SS-ADC) that has a novel high-speed counter and can reduce temporal noise in a wide range of frequency ...

In this episode, I look into a groundbreaking new development from Sandia National Laboratories. The US military has created a next-generation quantum motion sensor that could make munitions ...

Abstract: In recent years, pressure sensors have been widely used as crucial technology components in industrial, healthcare, consumer electronics, and automotive safety applications. With the ...

While fluorophore-biomacromolecule systems are relatively well known, afterglow luminophore-biomacromolecule conjugates/complexes are rarely studied. Here, the authors report the development of a ...

Patients are being warned to stop using some glucose monitors made by Abbott Diabetes Care after the company found malfunctioning sensors may be linked to hundreds of adverse events and several deaths ...

This top-rated ice maker from Whirlpool will let you hold up to 25 pounds of ice at a time, more than enough to cool down a pitcher of mint lemonade. This model uses special freezing technology to ...

Nanosensors are chemical or mechanical sensors that can be used to detect the presence of chemical species and nanoparticles, or monitor physical parameters such as temperature, on the nanoscale. They ...
