Measuring Virus Exposure Risk Using a CO2 Sensor While Traveling

hardaker writes: I wrote up the results from studying graphs of CO2 measurement data during a trip I took from Sacramento, California to London to attend the IETF-115 conference. Since CO2 is considered to be a potential proxy for measuring exposure to airborne viruses, it provided me with a rough guess about how safe (or not) I was at various points of my travel. TL;DR: big conference rooms: good, busses: bad, everything else: in between. "Numbers alone do not effectively measure risk absolutely," the page concludes. "You must combine numbers with logic and common sense. Airlines with good filtering systems are likely ok. But do aim the fans at you with maximum air flow..." "Hallways and crowded coffee tables are where we need to worry the most. Unfortunately, the masking policy at IETF-115 was sort of backward: in the rooms the circulation was quite good, but in all my graphs you can see a spike as I wandered from one room to another, and this is where masking policies were more lax allowing participants to remove their masks."
