This Gas Sensor detects Methane, Butane, Propane, alcohol, hydrogen, LPG & smoke. Flammable & combustible gases are detected by the onboard heater which sends an analog signal that increases as the concentration of flammable gases increases. This module also includes a digital output pin with TTL output. The Potentiometer on board is used to set the Digital Output Setpoint.
