The Portable Air Quality Monitor We Couldn’t Find - Built Openly, Built Together

AirGradient Blog
#1

Interest in a portable AirGradient monitor has been building for a long time. We’ve heard it from customers who want something they can take with them day to day, from researchers who need a device that can move easily between environments, and internally from our own team. The idea kept resurfacing, and the same question always followed: if we were going to carry a portable air quality monitor ourselves, what would it actually need to be?

This is welcome news indeed. I have been using the Aranet 4 for to monitor CO2. Apart from the obvious monitoring my office at work (e.g., how long can I keep the door shut for before CO2 builds up too much), I also use it for deciding when to use a mask (for infection control) in public spaces, meetings, and on transport.

This has provided insights such as our car needs to be on a moderate fan setting and definitely not on the recirculating setting, commercial flights can have CO2 values over 2500 ppm
(I hope the pilots have fresher air than the passengers).

I would find it valuable to have particle monitoring as well. With regard to sensors, CO2, particles, temperature, and humidity are all that I would be after. The Aranet has a pressure sensor but, other than identifying flights, I don’t find it useful.

Yes, PM, CO2, Temperature and Humidity are definitely set to be included. We are also looking on potentially adding Pressure, and VOCs.

The pressure sensor can be helpful in calibrating altitude impacts on the CO2 measurements.

Super excited for this one. What is the best way to follow along?

+1 for pressure sensor. The pressure sensor could also be used to predict the weather. GitHub - HAuser1234/homeassistant-local-weather-forecast: Homeassistant local weather forecast. ~90% accurate*
