The MQ3 alcohol sensor is simple to use and has two different outputs. It provides not only a binary indication of the presence of alcohol, but also an analog representation of its concentration in the air. The analog output voltage of the sensor (at pin A0) varies proportionally to the alcohol conc..

The MQ7 is a simple-to-use Carbon Monoxide (CO) sensor suitable for sensing CO concentrations in the air. It can detect CO-gas concentrations anywhere from 20 to 2000ppm. MQ7 is a high sensitivity to carbon monoxide and stable and long-life span.FeaturesFast response and High sensitivity.Stable and ..
