@russss@chaos.social how did you end up doing #CO2 monitoring at #emfcamp? Between #fosdem and #eventinfra we are close to spending 10k€ on #airgradient because they do most things right, and we were not able to get our own hardware spun up. Intention is for everything to go into the eventinfra loan pool so ALL the conferences can monitor their environments. Before we make that step, we wanted to check if it makes sense to collaborate on fully open hardware, firmware, and software stack instead.
