Elevated ranges of CO2 result in decreased cognitive potential and facilitate transmission of airborne viruses, which may linger in poorly ventilated areas for hours. The extra CO2 within the air, the extra virus-friendly the air turns into, making CO2 information a useful proxy for tracing pathogens. Actually, the Australian Academy of Science described the air pollution in indoor air as “someone else’s breath backwash.” Kawaiicon organizers confronted operating a big infosec occasion throughout a measles outbreak, in addition to consistently rolling waves of Covid-19, influenza, and RSV. It’s a well-recognized ache level for convention organizers annoyed by large gaps in public well being—and lack of management over their venue’s clear air requirements.
“In general, the Michael Fowler venue has a single HVAC system, and uses Farr 30/30 filters with a rating of MERV-8,” Kawaiicon organizers explained, referencing the filtration choices in the space where the convention was held. MERV-8 is a budget-friendly choice–standard practice for homes. “The hardest part of the whole process is being limited by what the venue offers,” they explained. “The venue is older, which means less tech to control air flow, and an older HVAC system.”
Kawaiicon’s work started one month earlier than the convention. In early October, organizers deployed a small fleet of 13 RGB Matrix Portal Room CO2 Screens, an ambient carbon dioxide monitor DIY challenge tailored from US electronics and package firm Adafruit Industries. The screens have been related to an internet-accessible dashboard with reside readings, every day highs and lows, and information historical past that confirmed attendees in-room CO2 tendencies. Kawaiicon examined its CO2 screens in collaboration with researchers from the College of Otago’s public well being division.

“That’s awesome,” says Adafruit founder and engineer Limor “Ladyada” Fried about the conference’s adaptation of the Matrix Portal project. “The best part is seeing folks pick up new skills and really understand how we measure and monitor air quality in the real world (like at a con during a measles flare-up)! Hackers and makers are able to be self-reliant when it comes to their public-health information needs.” (For the full specs of the Kawaiicon build, you can check out the GitHub repository here.)
The Michael Fowler Centre is a spectacular mix of Scandinavian brutalism and inside woodwork designed to boost sound and air, together with two grand pou—carved Māori totems—subsequent to the principle entrance that rise by means of to the higher foyers. Its cathedral-like acoustics posed a problem to Kawaiicon’s air-hacking crew, which they solved by putting the RGB screens in stereo. There have been two on every stage of the Important Auditorium (4 whole), two within the Renouf session area on stage 1, plus screens within the daycare and Kuracon (youngsters’ hacker convention) areas. To prime it off, screens have been positioned within the Quiet Room, on the Registration Desk, and within the Inexperienced Room.

“To be honest, it is no different than having to consider other accessibility options (e.g., access to venue, access to talks, access to private space for personal needs),” Sput wrote. “Being a tech-leaning community it is easier for us to get this set up ourselves, or with volunteer help, but definitely not out of reach given how accessible the CO2 monitor tech is.”
Kawaiicon’s attendees might rapidly verify the situations earlier than they arrived and determine learn how to defend themselves accordingly. On the occasion, WIRED noticed attendees checking CO2 ranges on their telephones, masking and unmasking in numerous convention areas, and watching a show of all room readings on a dashboard on the registration desk.
