We present a novel non-dispersive infrared (NDIR) CO2 gas sensor with a light source emitting collimated light. Using this thermopile, we also have successfully developed a small, sensitive NDIR CO2 detector module for accurate air quality monitoring systems in energy-saving building and automotive applications. The novel sample cavity comprising specular reflectors around the light bulb is configured to uniformly emit collimated light into the entrance aperture of the cavity in order to enhance the sensitivity of NDIR CO2 detector.
