Jeff Fortin T.At 280 canadian pesos (taxes included), the legendary <a href="https://mastodon.social/tags/Aranet4" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Aranet4</a> e-ink portable CO2 air monitor is stupidly expensive, but I'm really tempted to buy one nonetheless… for upcoming conferences/events attendance, essentially to decide when an auditorium is worth masking up in, or a room best avoided if poorly ventilated, as CO2 concentration is presumed to be a reasonably proxy measurement of air quality, and thus the risk of CoViD infection 🤔<a href="https://mastodon.social/tags/airquality" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#airquality</a> <a href="https://mastodon.social/tags/COVIDisAirborne" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#COVIDisAirborne</a> <a href="https://mastodon.social/tags/conferences" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#conferences</a>

ikuo<a href="https://todon.eu/@EmbodiedEthics" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@EmbodiedEthics</a> This app is fantastic. Very easy to use. I don't go into indoor public spaces often, but when I do, I always try to bring my Aranet CO2 monitor and submit a reading. It's been great seeing more U.S. measurements on the map but we still need a lot more users to catch up with Germany! 😁<a href="https://indoorco2map.com/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://indoorco2map.com/</a><a href="https://mas.to/tags/Aranet" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Aranet</a> <a href="https://mas.to/tags/Aranet4" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Aranet4</a> <a href="https://mas.to/tags/CO2Monitor" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CO2Monitor</a>

Scott LairdAt <a href="https://hachyderm.io/tags/grafanacon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#grafanacon</a> in Seattle today. So far, CO2 levels have been impressive; after an hour in the keynote room, CO2 has peaked at 499 PPM.The highest reading so far today was actually in my car while driving.<a href="https://hachyderm.io/tags/aranet4" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#aranet4</a>

fritzoidsThe tiny theater was about 1/3 full and during the 2h that we were there the CO2 never went above 800ppm. I think this might be because they have a very old-fashioned ventilation system that is just continuously on full blast (two years ago they still had the info about their ventilation system on their website... but that apparently got removed.) <a href="https://mas.to/tags/IndoorAir" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#IndoorAir</a> <a href="https://mas.to/tags/Aranet4" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Aranet4</a> <a href="https://mas.to/tags/CleanAir" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CleanAir</a>

Markus 👨‍💻Für solche Dinge ist es sehr praktisch, dass man auf einem Mac auch einfach iOS-Apps installieren kann. <a href="https://mastodon.social/tags/Aranet4" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Aranet4</a>

Markus 👨‍💻Letzte Woche einen <a href="https://mastodon.social/tags/Aranet4" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Aranet4</a> frust-geshoppt. So aus Neugierde, wie häufig ich zu Hause lüften sollte und wie sich die Werte über Nacht so verändern. Heute aus Neugierde in den Zug mitgenommen.

KanaMaunaSweet. In an old crowded conference room meeting with 100 people and I’m the only one masked. <a href="https://sauropods.win/tags/AraNet4" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#AraNet4</a> readings don’t look good either. And on the 5th anniversary of the pandemic.

HelmutIch bin mit dem Aranet 4 Home (Temperatur, Luftfeuchtigkeit, Druck, CO2) seit längerer Zeit zufrieden - selbstverständlich eingebunden in Home Assistant. Vielleicht hole ich uns noch ein zweites Exemplar, da es derzeit -30% gibt. <a href="https://wien.rocks/tags/smarthome" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#smarthome</a> <a href="https://wien.rocks/tags/aranet4" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#aranet4</a> <a href="https://wien.rocks/tags/homeassistant" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#homeassistant</a><a href="https://www.aranet.com/en/home/products/aranet4-home" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.aranet.com/en/home/products/aranet4-home</a>

David HembrowThis doesn't look good. I mean, a reduction in atmospheric CO2 might be nice (perhaps not this much of a reduction), but my device displaying 255 ppm CO2 immediately after calibration probably just means that it's faulty.After I took it indoors the display rise above 300 for a few minutes and then it started displaying error 0x8002.Anyone out there seen this fault before? <a href="https://todon.eu/tags/Aranet4" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Aranet4</a> <a href="https://todon.eu/tags/aranet" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#aranet</a> <a href="https://todon.eu/tags/co2sensor" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#co2sensor</a> <a href="https://todon.eu/tags/co2" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#co2</a>

fritzoidsThere was a parent teacher conference today for the parents of all the 7th graders. The room had been occupied by the parents of all the fifth graders for about 60minutes before that. <a href="https://mas.to/tags/IndoorAir" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#IndoorAir</a> <a href="https://mas.to/tags/Aranet4" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Aranet4</a>

dasgrueneblattIch hab seit einiger Zeit einen <a href="https://wien.rocks/tags/Aranet4" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Aranet4</a> tragbaren CO2-Sensor und inzwischen ein paar interessante Sache gelernt:0. Wenn ich wissen will, wie die Luftqualität an einem Ort ist, muss ich den Sensor dorthin mitnehmen und darf ihn nicht zu Hause oder in der Garderobe vergessen. Das ist erstaunlich schwierig, aber ich lerne es langsam. :masto_silly:1. (Viel) niedrigere Werte als erwartet: Wiener Ubahnwaggons(!), große Supermärkte, volle Railjetgarnituren, das gesamte Klinikum St. Pölten inkl Kaffeehaus.2. (Viel) höhere Werte als erwartet: Saal 2 im Dschungel Wien Theater, halbvolle Cityjet-Schnellbahngarnituren, Technisches Museum, Kaffeehaus Der Mann Perfektastraße, im Freien.3. Die anderen Werte sind wie erwartet. Also je mehr Leute, je länger, je kleiner und geschlossener der Raum, desto höher klettert der CO2-Wert. Ich war letztens fast drei Stunden in einer Besprechung mit neun Personen, und der Raum war groß und hatte eh eine Belüftung, aber wir waren zum Schluss trotzdem bei rund 3000. Ich war zwei Mal im selben kleinen Sushilokal. Beim ersten Mal war ich positiv überrascht, wie niedrig der Wert war, beim zweiten Mal war ein Tisch mehr besetzt, und der Wert war viel höher.4. Was tun mit der Information? Der CO2-Wert an sich ist ja uninteressant. Weil er leicht und günstig zu messen ist, wird er als Proxy für "verbrauchte" oder "schlechte" Luft verwendet. (Richtig hohe Werte erkennt eins aber sowieso auch mit den körpereigenen Sensoren.) Hohe Werte können vielleicht zu erhöhter Vorsicht mahnen, aber was sagen niedrigere Werte wirklich aus? Eine mittelvolle U6 hat tatsächlich Werte deutlich unter 1000, aber ich lass die Maske auf. Dasselbe gilt für den Supermarkt. Wenn mir jemand gegenüber sitzt oder direkt neben mir steht und in die CO2-arme Luft hustet oder niest, ist das ja trotzdem ansteckend. 5. Ich bin sehr dafür, öffentliche Räume mit besserer Luft auszustatten. Allein für die Konzentration beim Arbeiten, beim Lernen, beim Kunstgenuss zahlt es sich aus. Und die genieste Keimwolke verzieht sich viel schneller und hängt nicht noch eine Viertelstunde später unsichtbar in der Luft. Ansteckungen würden auf die unmittelbare räumliche und zeitliche Umgebung reduziert. <a href="https://wien.rocks/tags/saubereLuft" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#saubereLuft</a> <a href="https://wien.rocks/tags/wien" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#wien</a> <a href="https://wien.rocks/tags/niederosterreich" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#niederosterreich</a> <a href="https://wien.rocks/tags/noe" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#noe</a> <a href="https://wien.rocks/tags/%C3%B6sterreich" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#österreich</a>
