sensor.community is probably the larger CO2 map, as it currently has 12,236 active sensors compared to Airgradient's 500 sensors [1]. They also offer instructions for the construction of sensor kits or the purchase of pre-assembled units. The CCC has an interesting presentation about its mission and approach [2]. How do you differentiate yourself from sensor.community?

/edit: My mistake: sensor.community focuses on PM2.5 µg/m³ while you provide CO2 information. Please excuse my mistake.

I would disagree with that. We have quality measures to assess what 'better' can mean in software engineering (e.g. maintainability, reliability, security, performance, etc.). You are right that it is not fixed what is most important. It may vary from one organization to another, but it can be conceptualized and then made measurable to some degree.
