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

In this paper, we propose a novel, miniaturized non-dispersive infrared (NDIR) CO2 sensor implemented on a silicon chip. The sensor has a simple structure, consisting of a hollow metallic cylindrical cavity along with access waveguides. A detailed analysis of the proposed sensor is presented. Simulation with 3D ray tracing shows that an integrating cylinder with 4 mm diameter gives an ...

CO2 Sensors for Smart Applications - EEWeb

15/10/2019· Non-dispersive infrared (NDIR) sensors are the most common type used to measure CO 2. In NDIR, an infrared lamp directs light waves through a tube filled with an air sample to an optical filter in front of an IR light detector. The detector measures the amount of light that passes through the optical filter. The band of IR radiation produced by the lamp is very close to the ...

How does an NDIR CO2 Sensor Work? |

Modern NDIR CO2 sensors. Today's newest generation of CO2 sensors has even more optimized waveguides, allowing a longer optical light path to be folded into an even smaller. 8 mm x 33 mm x 20 mm footprint. In addition to a smaller size, new mid-range infrared light-emitting diode (LED) light sources have been developed that allow NDIR sensors to operate at much lower power levels. Combined ...
