The MQ series is a popular family of gas sensors, each designed to detect specific gases or a combination of gases.1 Here are some of the most common MQ sensors and the gases they can detect:
- MQ-2: Methane, Butane, LPG, Smoke2
- MQ-3: Alcohol, Ethanol, Smoke3
- MQ-4: Methane, CNG Gas4
- MQ-5: Natural gas, LPG5
- MQ-6: LPG, Butane gas6
- MQ-7: Carbon Monoxide7
- MQ-8: Hydrogen Gas8
- MQ-9: Carbon Monoxide, Flammable Gases910
- MQ131: Ozone11
- MQ135: Air Quality (CO, Ammonia, Benzene, Alcohol, Smoke)12
- MQ136: Hydrogen Sulfide13
- MQ137: Ammonia14
- MQ138: Benzene, Toluene, Alcohol, Acetone, Propane, Formaldehyde, Hydrogen15
- MQ214: Methane, Natural16 gas17
It's important to note that while these sensors are capable of detecting the listed gases, their sensitivity and accuracy can vary depending on factors like temperature, humidity, and the presence of other interfering gases
