The MQ-9  is a simple-to-use, low-cost gas sensor. It is highly sensitive to concentrations of LPG, carbon monoxide, and methane in the air and outputs its reading as an analog voltage. The sensor can measure concentrations of 10-1000ppm of CO,  100-10000ppm methane,  and 100-10000 ppm LPG. It is very stable with a long life and low power consumption. The MQ-9 is valuable for detecting gas leaks in a home or build-up of toxic carbon monoxide.
