Sensor for highly accurate carbon dioxide measurement


Sensirion is introducing the SCD30 – a humidity, temperature and carbon dioxide concentration sensor.

CMOSens technology for IR detection enables highly accurate carbon dioxide measurement. 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. The very small module height allows easy integration into different applications.

Carbon dioxide is a key indicator of indoor air quality. Thanks to new energy standards and better insulation, houses have become increasingly energy efficient, but the air quality can deteriorate rapidly. Active ventilation is needed to maintain a comfortable and healthy indoor environment, and to improve the well-being and productivity of the inhabitants.

Sensirion’s SCD30 offers accurate and stable CO2, temperature and humidity monitoring. This enables customers to develop new solutions that increase energy efficiency and simultaneously support well-being. With the new SCD30, Sensirion has expanded its portfolio to include environmental sensor for air quality measurement.
