This module provides an introduction to utilizing a gas sensor with the Arduino. It also demonstrates some warning systems that can be implemented with the sensor. Finally, it provides a sensor ...

If you believe that a PM2.5/10 sensor can also detect O1, NO2, SO2 then go right ahead and market it as an “Air Quality” sensor. I look forward to the law suits.

To prevent the sensor from receiving too much noise during flight, the sensor was soldered to an Arduino ProtoShield on the pins. The other end of the 9DOF was glued to the shield.
