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

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

Abstract: In this work, we report a self-compensating, label-free, and anti-interference surface plasmon resonance (SPR) fiber biosensor based on a cascaded U-shaped multimode fiber and a single-mode ...

Abstract: Magnetic field sensor devices have been widely used to track changes in magnetic flux concentration, and the Hall sensors are promising in many engineering applications. Design optimization ...

Feed historical statistics into Home Assistant database. HomeAssistant architecture is built around polling (or pushing) data from devices, or data providers, in "real-time". Some data sources (e.g, ...
