 Look at this little beauty. This is my product pick of the week this week. It is the A&S 160 Mox Gas Sensor with Stema QT. It's plugged in with a Stema QT cable over I squared C to a QT Pi right there. I have a little readout here showing air quality index, organic compounds, and then the CO2 level, which is parts per million. I'm just going to breathe on it from pretty nearby. You'll see that level start jumping up there. My CO2 levels jumped up to, what, a thousand or so. I'm going to stink it up with this paint marker. So you can use this for, watch these values here. I'm just setting this paint marker. Wow, the volatile compounds was jumping up in the five thousands there when this first landed. It is the A&S 160 Mox Gas Sensor.
