A comprehensive Arduino-based gas detection and security system that combines gas sensing capabilities with password protection. This project uses an MQ-2 gas sensor to detect various gases and ...

The BME280 sensor was easier to set up, as it communicates over the I2C serial protocol. This means that we only needed to ...

This project utilizes an Arduino Uno CH340G development board paired with a DHT11 temperature and humidity sensor to create a compact yet capable environmental monitoring system. It measures ambient ...

Abstract: A two-component gas sensor based on Quartz-Enhanced Photoacoustic Spectroscopy (QEPAS) and Light-Induced Thermoelastic Spectroscopy (LITES) was realized by the time-division multiplexing ...

Abstract: Smart contracts are automated programs stored on a blockchain, featuring unique attributes such as permissionlessness, trustlessness, immutability, and transparency. These properties ...

China’s microelectromechanical systems (MEMS) sensor industry is surging, but technical gaps, fragmented production and coordination challenges hinder its full potential. As global demand accelerates, ...
