The sensor assumes it sees fresh air (about <a href="https://climate.nasa.gov/vital-signs/carbon-dioxide/?intent=121" target="_blank" rel="noopener">420 ppm</a>) at least once a week and corrects its baseline to match. Turn it off if the device sits in a space that rarely gets fresh air, then calibrate manually with **Calibrate SCD40 To 420ppm** every 1 to 2 years. |
