How Accurate Is the Sensirion SGP41 TVOC Sensor?
AirGradient air quality monitoring.
Instead, they’ve both made the decision to show relative indexes, which represent increasing or decreasing VOC levels in place of absolute values (such as concentration in parts per billion). High reproducibility is a key indicator of precision, meaning that the sensors can reliably measure changes in VOC levels without significant variability between individual devices of the same model. Bottom line: The TVOC sensor demonstrates the ability to detect qualitative changes in VOC concentrations, accurately capturing trends in rising or falling levels.
