This project is a safety monitoring system designed to detect hazardous gas leaks using an MQ2 gas sensor interfaced with an Arduino UNO. The MQ2 sensor detects gases such as LPG, methane (CH₄), ...

This project uses an MQ2 gas sensor, relay module (for motor or exhaust fan), buzzer, and LEDs to create a complete gas leakage detection and alert system using Arduino. When gas concentration crosses ...

Abstract: LPG is an alternative fuel used for daily use. Due to its low cost and ease of installation. This article covers an Arduino-based gas detection system that uses an Arduino UNO R3 board and ...

Gas leaks can pose serious safety risks, especially in homes, kitchens, and small commercial spaces. In this project, you'll learn how to build a simple and budget-friendly gas leakage detector using ...

In today's lecture, we will design a project in Proteus, where we will Interface Gas Sensor with Arduino. I will provide the complete code and simulation. Gas sensors are widely used in fire alarms, ...

本日は、IoT環境の整備を目的として、複数のRaspberry Piを使用したシステム構築を行った。主な成果として、Raspberry Pi Zero WでMQ2ガスセンサーの監視システムを構築し、Raspberry Pi 4にPi-holeとVPN環境を設定した。また、運用上の問題により、Home Assistantは削除する ...

Abstract: This project presents a fire-fighting robot designed to autonomously detect and extinguish fires. The robot utilizes Arduino as its microcontroller, incorporating various sensors and ...
