Cool product! I come from a measurement/calibration background, so I'm curious about the accuracy of your system. Have you tested this against lab equipment, or do you have plans to specify accuracy with proper tolerance intervals?

What about measurement uncertainty and unit-to-unit variability? I know this is consumer hardware, so I dont expect a full blown evaluation but have you characterized expected performance?

Thanks and good question! We have planned to do a proper lab test soon. The Swiss Federal Office for the Environment is a project partner and has such equipment. During the design phase, we used a software to model the air flow and particle movements through the enclosure. Until then, we can only state what is already specified in the SCD41 and SGP41 datasheets.
