This is an ultra-sensitive LPG sensor that beeps when it senses any gas leak.It can detect LPG vapors between 200 and 10,000 PPM and drive a piezoelectric buzzer to attract attention and take immediate action.The buzzer beeps until the concentration of gas in the air drops to a safe level.The circuit USES an MQ6 gas sensor designed to detect LPG, propane and isobutane gases.
