We tested popular wideband O₂ controllers against lab-grade equipment to see how accurate their lambda readings really are ...

Oxygen sensors detect the amount of oxygen in the exhaust. Oxygen sensors usually don’t have a replacement schedule. A bad oxygen sensor can be diagnosed with a code reader or scan tool. A car’s ...

Fingertip monitors known as pulse oximeters that can be used at home to detect low blood oxygen levels (hypoxemia) give ...

The independent technology information source for electronics engineers, programmers and developers.

Abstract: Wire retention force is an important indicator for evaluating the reliability of wire insertion in electrical connectors. Current approaches to measure this force are mainly relied on spring ...

Abstract: Capacitive liquid level sensors are attractive for applications requiring long-term reliability and resistance to corrosion, such as in environmental experiments or domestic water monitoring ...
