The MQ2 gas sensor module is highly useful for gas leakage detection at home or industry. The sensor module can detect h2, LPG, CH4, CO, Alcohol, Smoke or Propane. It is highly sensitive and very first responder. Depending on the requirements of sensitivity, the sensor can be adjusted with a Potentiometer.

The MQ3 gas sensor module is highly useful for gas leakage detection at home or industry. The sensor module can detect Alcohol, Benzine, CH4, Hexane, LPG, CO. It is highly sensitive and responding time is very fast. Depending on the requirements of sensitivity, the sensor can be adjusted with a Potentiometer.

The MQ7 gas sensor module is highly useful for carbon monoxide(CO) gas detection at home, car or industry. The sensor module can detect carbon monoxide(CO). It is highly sensitive and responding time is very fast. Depending on the requirements of sensitivity, the sensor can be adjusted with a Potentiometer
