Gas-Detector-With-Allarm - Continuously monitor combustible gas (LPG, methane, smoke) with an MQ-2 sensor. When the analog reading exceeds a user-defined threshold, trigger a visual (red LED) and audible (buzzer) alarm for a fixed duration, while a green LED indicates “safe” status. By Bocaletto Luca
