We are surrounded by invisible gases everywhere. While we generally don’t have to worry about them, under the right circumstances, they can be very combustible and dangerous. The MQ9 breakout board detects carbon monoxide, methane, propane, and other flammable gases so the right measures can be taken in time. The sensor detects carbon monoxide at 10-1000 ppm and other combustible gasses at 100-10000 ppm.
The digital and analog outs can be found on the through-holes. They are marked as DO and AO respectively. The digital output can be obtained by setting a threshold value with a potentiometer. The analog output will depend on the intensity of the gases.
