Product Details

Sensirion SCD30 CO2 sensor module

SENSIRION SCD30 sensor module for HVAC and indoor air quality applications. CMOSens® Technology for IR detection enables highly accurate carbon dioxide measurement at a competitive price. Along with the NDIR measurement technology for CO2 detection, a best-in-class Sensirion humidity and temperature sensor is also integrated on the same sensor module.

Ambient humidity and temperature can be outputted by Sensirion’s algorithm expertise through modeling and compensating of external heat sources without the requirement for any additional components. Thanks to the dual-channel principle for the measurement of carbon dioxide concentration, the sensor compensates for long-term drifts automatically by design.
