Infineon CO2 Sensor

The Infineon CO2 sensor is a real carbon dioxide sensor in an unprecedented small form factor. Designed on the basis of the photoacoustic spectroscopy concept. Infineon 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.
