"A gas leak detection system using a microprocessor to monitor LPG levels, trigger an alarm, and provide a manual reset option. Built with an MQ sensor, buzzer, and LED indicators." - ...
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 ...
