About This Arduino library is used for driving "Xadow - Mutichannel Gas Sensor" and "Grove - Mutichanel Gas Sensor" ...

This study presents a novel high-performance acetonitrile terahertz (THz) gas sensing system based on a flexible, low-loss Ag/PP THz hollow waveguide (HWG). The mathematical model of the established ...

I built an indoor air quality monitor to monitor air temperature and humidity using the DHT22 sensor. It also has an MQ-2 gas sensor to monitor LPG, smoke, and CO molecules in the air. esp8266 udp ...

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.

This article presents the design and development of a gas acquisition and control system utilizing the PIC16F877 microcontroller in conjunction with an MQ2 gas sensor and a Type K thermocouple for ...

Indoor air pollution poses a major global health threat, with complex chemical components and low detection standards being core issues. Due to intrinsic cross-sensitivity, a wide range of commonly ...
