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.
