In contrast, layered 2-D materials have large surface-to-volume ratio and excellent mechanical flexibility, making them one of the excellent materials to develop flexible gas sensors. In this work, we ...

This is a MH-Z19B / MH-Z19C CO2 sensor library for Arduino. It has been built from scratch to support hardware and software serial with a small footprint. The MH-Z19 is a NDIR (Non-Dispersive Infrared ...

Simple, accurate, portable, and selective gas sensors with autonomous, remote, and real-time access have become a requisite in various fields of applications. In this article, we report the ...

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 ...

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-Insulated switchgear (GIS) is prone to partial discharges (PDs) in high electric field environments, and the concentration of generated NO2 is an essential indicator for determining the PD types ...
