Adafruit Sgp30 Breakout Capteur de qualité de l'air – Voc ...

Orange line is TVOC, thick red line is eCO2 from the SGP30. White line is CO2 measured by a different sensor sitting next to my test rig. Notice how noisy the orange and red traces are compared to the white. As you can see, this graph covers some night-time where there is no activity in the building. In terms of CO2, it either over-reads or under-reads compared to the 'real' amount of CO2. I ...

Honeywell Air Quality Monitor

The HAQ CO2 sensor is calibrated at the factory, but may drift over time. To combat this, the HAQ should be calibrated on occasion to account for the drift. Calibration involves exposing the sensor to a known gas source (outdoor air, or indoor air in an unoccupied room - both should equal approximately 400 ppm CO2). The HAQ takes multiple readings, calculates an average, stores the difference ...
