I built a CO2 meter around a SCD30 five years ago: https://bbot.org/blog/archives/2024/05/19/pocket_co2_meter_b...

My takeaway is that it draws a lot more power than you'd expect, thanks to the incandescent light source, and unless there's quite a lot of airflow over the sensor, it'll exhibit self-heating at any poll rate under every ten minutes.
