Currently TVOC/eCO2 units are not very precise so it would be a good option to have a better solution to measure CO2. SCD41 is compact enough to be put in a unit, I think.
I was waiting for this unit too and luckily they have already presented it last Friday.
It would be great to have a Core that could be used on a vehicle, e.g. a motorcycle. So, either a special case or a separate device would be great to have around.
