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 ...

A pulse oximeter measures blood oxygen levels at home and in healthcare settings. Abnormally low readings on a pulse oximeter might require medical care, especially if they are below 92%. Skin color ...

China’s microelectromechanical systems (MEMS) sensor industry is surging, but technical gaps, fragmented production and coordination challenges hinder its full potential. As global demand accelerates, ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...

Abstract: Timely detection of abnormal pulse wave conditions can provide early warnings for cardiovascular emergencies. Strain sensors can detect subtle pulse wave changes, however, they often face a ...

If you have trouble breathing, your doctor may recommend a few tests to figure out what’s causing it. Some measure how much air you breathe in or out or how much oxygen is going from your lungs to the ...
