SGP30 VOC sensor only shows low co2e ... Adafruit Industries

+

· It''s nice to hear the eCo2 levels from the SGP30 sensor are close to what a higher end Co2 specific sensor reads also. I was wondering The SGP30 has the baseline calibration feature that the CCS811 lacks and that is what keeps it from showing random spikes in readings over time. From my experience, CCS811 just starts going crazy after a few days or running and you have to reset it to get …

Om het CO2 gehalte goed en accuraat te kunnen meten en/of regelen bieden wij een keuze uit een groot aantal CO2 sensoren, CO2 meters, CO2 regelaars. De keuze van de CO2 opnemer wordt bepaald door de toepassing. Voor gebouwautomatiseringsprojecten (GBS) volstaat een CO2 opnemer met 010V of met RS485 Modbus interface. De CO2 opnemer kan desgewenst worden uitgebreid met een …

Why does my CO2 sensor read zero after calibration?

The Carbon Dioxide IR sensor is calibration sensitive it needs to have a twopoint calibration performed in the proper order. Zero calibration with Nitrogen gas, zero air or any gas matrix that does not have CO2 to calibrate your baseline. Span calibration with 5000ppm (5%) CO2 gas. The 5000ppm Span value is the lowest span value that the ...
