2. If the sensor reports all data regularly, but sometimes only reports TVOC and CO2 data, you can double check the threshold settings on "Device Settings". If you set the threshold, the sensor will report the data when TVOC/CO2 meets the threshold. Meanwhile, the sensor will also reports all data based on reporting interval.

Overview | Adafruit SGP30 TVOC/eCO2 Gas Sensor | Adafruit ...

· Restarting the sensor without reading back a previously stored baseline will result in the sensor trying to determine a new baseline. The adjustement algorithm will be accelerated for 12hrs which is the Maximum time required to find a new baseline. The sensor adjusts to the best value it has been exposed to. So keeping it indoors the sensor thinks this is the best value and sets it to ~0ppb tVOC and 400ppm CO2eq. As soon as you expose the sensor …

How Does a TVOC Sensor Actually Work? Kaiterra

What the sensor is actually measuring is the electrical resistance of this metaloxide layer. This real time measurement and output of resistance is the first step in obtaining our TVOC reading. The change in resistance across the surface of the sensor is directly proportional to the change in concentration of the target gas(es). The exact degree to which the resistance will change (that is, the ratio or equation that …

· 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.
