California is suffering from fires all around us, and the SF Bay Area has terrible air quality. My Tempest is arriving tomorrow, and I wonder if there is a air quality sensor I could buy to also monitor air quality. Thanks for your help, Jeff

Here is another article on PurpleAir that was just published yesterday [image] How this small sensor startup became essential to helping California deal... PurpleAir’s network of air quality monitors and its real-time map have provided vital information to people looking to avoid bad heal…

Why Purple Air and Air Now may have different values: [image] Why PurpleAir and AirNow show different AQI scores during wildfires On a foggy Tuesday morning in Pacifica, AirNow.gov's Air Quality Index widget gave a value of 150 - unhealthy - for the 94044 zip code. With wildfires burning…

Thinking of Purple Air or Plume Labs Flow. Not sure if the Flow 2 is worth $70 more than the Flow 1, main difference seems to be that Flow 2 also measure PM1, in addition both Flow 1&2 measuring PM2.5, PM10, NO2, VOCs.

I had the flow 1 before the flow 2. In my opinion it wasn’t worth the upgrade. It’s battery operated, therefore mobile, but lasts only a day, so basically it is always in the charger. At some point the battery will give up. I would have preferred if it used wifi for 24/7 operation. Currently it only…

Liking the Flow, or Flow 2, since it also Measures NO2.

long discussion in Air Quality Sensor and a link to a page that explains the differences… Here near Tacoma we just went from AQI of 20 to AQI of 300 as a wall of smoke from the central Washington fires hit us. You could see it coming, the Cascades and MtRainier disappeared and we couldn’t even se…

there are many (too many) different AQIs in the world. Plume uses their own. [image] What is the Plume AQI? The Plume Air Quality Index (AQI)The Plume AQI gives you an immediate overview of what you are breathing, just as the temperature might give you a first indication of the weather o…

btw if you install the Plume labs Air Quality App(beta) you can select the USA aqi in the settings. but that doesn’t show your own device

Excellent new online map available at https://fire.airnow.gov/ lets you drill down visually, and includes permanent, temporary, and low-cost (Purple Air etc.) sensors.
