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 ...
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.

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 …
A nondispersive infrared (NDIR) gas sensor with an integrated optical gas chamber was designed to accurately detect multiple gas concentrations in a complex polluted environment. This chamber consists of a hexagonal prism shell and a reflection plate. In particular, six dualchannel infrared detectors for sensing different gases and one collimated infrared light source are integrated in the ...
