This project uses an MQ gas sensor and a buzzer with an Arduino Uno to detect gas leaks and issue an audible alert. The gas sensor is connected to analog pin A0. The buzzer is connected to digital pin ...

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: Significant safety dangers are posed by gas leaks in commercial, industrial, and residential environments. In order to improve safety and dependability in the detection and response to gas ...

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 ...
