NDIR CO2 gas sensing using CMOS compatible MEMS ScAlN ...

We use the NDIR approach, based on optical gas sensing, leveraging the change in light intensity when CO 2 gas molecules interact with light. As CO 2 gas molecules have a characteristic absorption line in the mid-infrared (IR) spectral region [ 22 ], a drop in the transmitted signal due to CO 2 gas molecules absorption is expected when light passes through the CO 2 gas.

On-Chip Non-Dispersive Infrared CO2 Sensor Based On an ...

Typically, NDIR CO2 sensors use the strong absorption of CO2 around m, a wavelength range where no other common molecules absorb, thereby avoiding cross-sensitivity issues. Due to these advantages, 83% of the European advanced CO2 sensor market uses NDIR sensors [4]. However, NDIR sensors tend to be bulky as a long (typically several cm)
