Sensitive LPG Leakage Alarm This project is an ultra-sensitive LPG sensor that generates loud beeps when it senses any gas leakage. It detects vapours of liquefied petroleum gas anywhere between 200 and 10‚000 ppm and drives a pies buzzer to catch attention for immediate action. The buzzer beeps until the concentration of gas in the air decreases to a safe level. The circuit uses an MQ6 gas sensor‚ which is designed to sense LPG‚ propane and isobutene gases.
