Description

Infineon has leveraged its knowledge in sensors and MEMS technologies to

develop a disruptive gas sensor for CO2 sensing. The XENSIVTM PAS CO2 is a real

CO2 sensor in an exceptionally small form factor based on the photoacoustic

spectroscopy (PAS) principle.

Infineon's MEMS microphone, which is optimized for low-frequency operation,

detects the pressure change generated by CO2 molecules within the sensor

cavity. CO2 concentration is then delivered in the form of a direct ppm readout

thanks to the integrated microcontroller. Highly accurate CO2 readings are

guaranteed.
