The Grove MQ9 Gas Sensor module is useful for gas leakage detecting (in home and industry). It can detect Carbon Monoxide, Coal Gas and Liquefied Gas.
 
The Grove - Gas Sensor module is useful for gas leakage detecting (in home and industry). It can detect LPG, I-Butane, Methane, Alcohol, Hydrogen, smoke and so on. Measurements can be taken as soon as possible based on its fast response time. Also the sensitivity can be adjusted by the potentiometer.
 
Each Grove - Gas Sensor Kit consists of one gas sensor base and four detectors, including MQ2, MQ3MQ5 and MQ9. Below is a contrast table of them. You can switch the detector on the base according to specific target gases.
 
  MQ-2 MQ-3 MQ-5 MQ-9
Detect Gas Combustible Gas、Smoke Alcohol Vapour LPG, Natural Gas, Town Gas Carbon Monoxide, Coal Gas, Liquefied Gas
Detect Concentration 300-10000ppm 0.04-4mg/L Alcohol 300-10000ppm 10-1000ppmCO;100-10000PPm Gas
