From the project

Hardware design, BOM, gerbers and 3D files for CO,-flammable-gasses-sensor-MQ9-breakout designed by Soldered Electronics.

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.
