How does an NDIR CO2 Sensor Work? |

Small NDIR CO2 sensor breakthrough. An engineering breakthrough occurred in 1993 when SenseAir AB patented a design for smallfootprint CO2 sensors. These sensors solved the size problem by using folded optics and metalized molded plastic to reflect the light through a curved shape (referred to as a ''waveguide'') that was longer than the footprint of the sensor module. The highly reflective coating ensured that the CO2 molecules inside the gas …

· Sensors continued to get smaller, when in 1993, an engineering breakthrough occurred; SenseAir AB patented a design for CO2 sensors with a smallfootprint. As a result, the size problem of the sensors was solved by using folded optics and metalized molded plastic. This was able to reflect the light through a curved shape (''waveguide'') that was lengthier than the footprint of the sensor module ...

Nondispersive infrared (NDIR) measurement of carbon ...

Abstract Nondispersive infrared (NDIR) gas detection has enjoyed widespread uptake as a result of development of devices in the standard miniature format for gas sensors, consisting of a cylinder with external dimensions of 20 mm diameter × mm height. We present a new design for such a sensor, making use of lowcost injection moulding technology.

Breakthrough in CO2 Measurement With a Chamberless NDIR ...

CO2 measurement using the nondispersive infrared (NDIR) gas sensing method is conventionally performed using a gas chamber as the main part of the sensor. In this paper, we report on a novel approach using a light source with an embedded parabolic reflector to measure CO2 concentrations above 400 ppm without the need for a chamber. Four alternative structures for CO2 detection were …
