Acetonitrile is widely used in pharmaceutical and industrial processes, but it is a volatile, flammable, and toxic gas. The rapid detection of trace acetonitrile gas is crucial for industrial ...

The development of photonic-based gas sensors using metal–organic frameworks (MOFs) and other microporous solids is often a multistep, complex process, typically involving MOF synthesis, purification, ...

Thus, they entered a heart rate sensor to our 2025 One Hertz Challenge! The build is based around a Wemos D1 mini, a ESP8266 development board.

Gas pressure sensors are essential in industrial and environmental monitoring. In this study, we propose and demonstrate an ultrasensitive and visually detectable gas pressure sensor based on a ...

We report a miniature optical fiber photothermal (PT) gas sensor with high sensitivity, fast response and large dynamic range. The sensing region is an air gap formed between the cleaved ends of two ...
