WEEK 6: WHAT WE HAVE DONE:
Gas sensors calibration
Material used:
- Wine preserver gas + vacuum bag
- Baseline calibration
As we mentioned in our previous blog, our first try to calibrate the gas sensors was using helium balloons and it did not work. It took a while for us to get the material we needed to do the calibration but now we are finally done with this process and we are ready to move on.
Gas sensors base values.
A new 3D-printed case
We made a stronger 3D-printed case. Our previous version of this case was made of ABS plastic which is a low quality material for our our case needs. Now, our new case id made of Uv cure resin plastic which is much better than the previous one. Our new 3D-printed case is stronger, soft, and manageable.
Our system broke
On the way to our midterm presentation we dropped off by accident the box that goes in the back of the bike. This was the only one box that we have ready to collect data and some of the components inside were damaged. We were sad because we were not able to show our system working in the presentation, but actually the dropping was a good happening since we were able to detect some weaknessess in our setting. So, now we are being working on the damages in our system and figure it out how to make it stronger.
NEXT STEPS
Our goals for week 7th are:
- Fix our broken box and build at least 3 more
- Collocate sensors at the Atlanta sensing station
- have at least three equipped bikes
- Get data and pilot data
