Adafruit SGP30 TVOC/eCO2 Gas Sensor

2020-12-07· 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 non-gas-related-events. To keep the values coming out reasonable, you'll need to calibrate the sensor. If no stored baseline is available …
