CO2 Sensor - PASCO2V01AUMA3

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.
