@dilekuz @davclark Please see attached edits and suggestions. Best, Vivek

(Can't attach PDF so could someone give me write permission to this repo?)

*Search if there are any sensors out there that already measure the air quality and share the data.
*Is there public data from sensors of unknown quality, if so then testing those air sensors would potentially make such data more useful.

Conduct a survey using amazon mechanical Turk asking people if they would be interested in knowing the air quality data nearby. If they would be willing to pay. If so how much (50, 100, ?).

It seemed like there was some discussion between @vhutheesing and @dilekuz but no feedback posted. I'll ping the carpool project about this. Please post your feedback here!

Got this feedback from Ron Cohen:

In our experience step 1 is to show the low cost sensor you are proposing to use has an interpretable response to humidity and temperature variations that occur on the time scale of atmospheric humidity and temperature variations. You should do that in the lab in a chamber that has zero signal before anything more complicated. Most of the sensors for CO, O3, NO and NO2 on the market have temperature and water response functions that are so strong and complicated that is is difficult to extract a reliable outdoor measurement. We are working with some of the low cost sensors http://beacon.berkeley.edu/ and would be willing to help with calibration--delivering known quantitites of gases at varying T and RH, but only after you can show that whichever ones you are using are potentially interpretable.

After a lab cal, we can probably find a field site with data, but that is more difficult and involves more people.

I've asked if we could work with him on obtaining access to a reasonable lab environment.

This should move to a Jekyll site or the wiki (linked at right!):
