Gas Leak Detector Arduino Project 🧯using MQ Sensor , Buzzer & LCD I2C
Gas Detector Project using Arduino UNO
In this project, I built a gas leak detection system that can sense flammable gases like LPG or methane using an MQ sensor.
When the gas concentration crosses a safe limit, the buzzer beeps to alert, and the LCD display shows a real-time warning message
