Measure real CO₂, not a guess. The SCD-41 uses Sensirion's photoacoustic NDIR technology to detect actual CO₂ molecules, unlike cheap "eCO₂" sensors that just estimate levels from VOCs. You get accurate carbon dioxide readings plus onboard temperature and humidity, all from one of the smallest true CO₂ sensors on the market.
