Really interesting seeing all your experiments and the results. I wonder if the difference in office and outdoor readings is related to the temperature difference?</p> <p>I had another idea for an experiment scenario: perhaps you could try running it in your car next time you go for a drive and see what the levels are like during a journey? I do wonder how much nasty pollutants make it into the inside of the car? You could save the results to a SQLlite database (or CSV file) and then upload to your dashboard when you get back.</p><img src="https://community.element14.com/aggbug?PostID=24692&AppID=381&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/challenges-projects/design-challenges/summer-of-sensors-design-challenge/b/blog/posts/in-the-air-tonight---testing-the-effects-of-an-ionic-air-filterSun, 30 Oct 2022 23:38:11 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:6cec1b5f-0cfc-41c1-a830-e64713ee16abdougw1<p>Does your sensor suite measure CO2? Often air quality is measured by CO2 concentration. We have fairly clean air here so the 2 big factors for air quality here are CO2 and pollen count. My particle detectors don&#39;t do a good job of detecting pollen, so I can only monitor CO2. It is surprising to me how the area where I work has significant CO2 build-up over the course of an hour, even though it has what I think is reasonable ventilation. The CO2 concentration doubles, although that is still well below dangerous levels.</p><img src="https://community.element14.com/aggbug?PostID=24692&AppID=381&AppType=Weblog&ContentType=0" width="1" height="1">
