The MQ-2 sensor is an adaptable gas sensor equipped for distinguishing an extensive variety of gases including liquor, carbon monoxide, hydrogen, isobutene, melted oil gas, methane, propane and smoke. This module has both a 3 pin male header interface and a "woods" style connector.
Structure and configuration of MQ-2 gas sensor is shown as Fig. 3, sensor composed by micro AL2O3 ceramic tube, Tin Dioxide (SnO2) sensitive layer, measuring electrode and heater are fixed into a crust made by plastic and stainless steel net. The heater provides necessary work conditions for work of sensitive components. The enveloped MQ-2 have 6 pin, 4 of them are used to fetch signals, and ...
The analog signal from MQ2 Gas sensor is further fed to LM393 High Precision Comparator (soldered on the bottom of the module), of course to digitize the signal. Along with the comparator is a little potentiometer you can turn to adjust the sensitivity of the sensor. You can use it to adjust the concentration of gas at which the sensor detects it. The sensor is sensitive to multiple gasses ...
