Recommendation for CO2 sensor

[Em_Ka]

Could I use the SCD41 for Mycodo?

Yes, the SCD-40 and -41 is supported: Supported Inputs: SCD-4x I use the SCD-30 because it’s a higher quality sensor, but the SCD-41 should work find for most applications.

If size doesn’t matter, i would go with the SCD30, almost same price.
