DatasheetProduct Overview
The XENSIV™ PAS CO2 is a real CO2 sensor combining NDIR technology with Infineon’s high SNR MEMS microphones, allowing for state-of-the-art accuracy in an exceptionally small form factor.
The sensor is based on the photoacoustic spectroscopy (PAS) principle, where CO2 molecules within the sensor cavity absorb infrared light, generating small pressure changes that are detected by an acoustic detector. CO2 concentration is then delivered in the form of a direct ppm readout, thanks to the integrated microcontroller. Highly accurate CO2 readings are guaranteed.
