Steps to calibrating air sensor (SCD30 CO2)?

Projects General Guidance

Hi,

A bit daft but I have some fundemental questions about how to calibrate the SCD30 CO2 sensor, such as what order to do thing in...

i.e. how long to leave sensor in fresh air, does the sensor retain the setting etc..

I posted on the official forum, please take a look if you can help :slight_smile:

Do you have a container with a known concentration of CO2? If not, you will have to use the Automatic Self Calibration which needs fresh air and continuous operation for about five days.

Hi John,

No container I'm afraid, I could use the ASC and leave it outside I guess. Will it retain the base level value?

Otherwise could I take the average in the area e.g. 414ppm and force that value in my sketch do you think?

Thanks
