Soldered 333102 Butane, LPG & Smoke sensor MQ2 breakout
Description
The MQ2 gas sensor detects the presence of various gas groups, such as gasoline and oil vapors, butane, propane, methane, ethanol (alcohol), hydrogen, smoke, and more. It responds best to liquids, but since we are rarely in such a situation, it also detects gases quite well. It requires only a short time to heat up to function properly.
The breakout board operates with both digital (DO) and analog signals (AO). The digital output is obtained by setting the thresholds with the potentiometer. The analog output varies according to the gas intensity around the sensor.
