Intro to Gas Sensor Plugs

Gas sensor are widely used in DIY projects today, hence we decided to make plugs for the  entire set of  MQ series sensors which operate in 5 volts.



The sensitivity of each sensor is as follows:

  • MQ2:  Methane, Butane, LPG & smoke.
  • MQ3:  Alcohol, Ethanol & smoke.
  • MQ4:  Methane & CNG Gas
  • MQ5:  Natural gas & LPG
  • MQ6:  LPG & butane gas
  • MQ7:  Carbon Monoxide
