Adafruit SGP30 TVOC/eCO2 Gas Sensor

· All VOC/gas sensors use the same underlying technology: a tin oxide element that, when exposed to organic compounds, changes resistance. The ''problem'' with these sensors is that the baseline changes, often with humidity, temperature, and other nongasrelatedevents. To keep the values coming out reasonable, you''ll need to calibrate the sensor. If no stored baseline is available …

The Eco Sensors C21 responds to most reducing VOCs, but not with the same degree of response for each VOC. The response is essentially logarithmic. For the first half of the scale (to about the 2nd yellow bar), the response is approximately linear. After that, it gets sharply logarithmic (much more concentration is required to get to the next bar than from the preceding bar). For example ...
