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
