Taking the CO sensor out for a spin

I took the CO sensor out into the car and took the car out for a spin, my idea was to attempt to record how much and when the motor vibrated when it detected CO. I tried these in various situations;
with the windows up/down, while revving/changing gear and when smoking in the car. i found that the motor vibrated most vigorously at its peak  when the window was down and when the car was slowing down in traffic.



the video is poorly as i needed to multitask between holding the camera in a good view, focusing the camera and smoke and take note on when it vibrated the most at the same time (if that helps as an excuse), you can see and mostly hear that near the end of the video the motor was vibrating harshly as it was at its peak of the situation i mentioned before.
