As the pandemic began, we covered the maker’s civic response in a series of articles and videos that we called Plan C. As we now expect a gradual return to normal activity, approaching an end of the pandemic, we call this new series Plan CO2 — how we might get back together safely.
The science is increasingly clear about the airborne transmission of Covid-19, which is to say that people spread it through aerosols — droplets suspended in air. Meeting people in closed spaces indoors is riskier than outdoors, and well-ventilated rooms are less risky. Not only can we not see a virus, we can’t really see what’s in the air around us. How do we know if a room is properly ventilated and windows and doors are open long enough?
Join Dale Dougherty of Make: and a panel of makers and experts working on C02 monitoring—including Guido Burger, Stephan Schulz, and Jeremy Hanson—for discussion and demonstrations of CO2 device monitoring. Show us what you’re working on or learn how to get started. We want to encourage more people, in particular students, to build a CO2 device.
Monitoring carbon dioxide (CO2) levels in an indoor space can provide real-time feedback on room ventilation. You can buy commercial CO2 devices but you can also build your own using readily available components that are familiar to most makers. This is a perfect project for students to build for their classroom. It has all the elements of a sophisticated Internet of Things (IoT) application, even though it is quite simple. You have hardware — a microcontroller connecting a CO2 sensor and some kind of display; and software — you can write the code for this application in a block-programming language in less than 10 minutes. It also produces a data feed that you can log and turn into charts that show the readings over time.
