Hacker events are often associated with lively, sometimes crowded environments that can lead to health concerns, such as the spread of illnesses. Recognizing this, New Zealand’s leading hacker gathering, Kawaiicon, took a groundbreaking step by implementing a dedicated, real-time air quality monitoring system across the venue.

Prior to the event on November 6, organizers installed DIY carbon dioxide sensors throughout the Michael Fowler Centre. These devices provided live data on air freshness, accessible via an online dashboard. Attendees could check the air quality in different areas—session rooms, kids’ zones, and the front desk—before arriving, promoting transparency and safety.

Security industry veteran Jeff Moss, founder of Defcon and Black Hat, praised this initiative, calling it “a remarkable example of hacking ingenuity.” He highlighted that CO₂ levels serve as a practical indicator of occupancy and ventilation, yet affordable, network-based monitoring solutions are scarce. The Kawaiicon approach exemplifies how creative problem-solving can enhance safety in tech communities.
