How Do CO2 Sensors Work?

How NDIR CO2 Sensors Work. NDIR CO2 sensors monitor and detect for the presence of carbon dioxide based on the absorption of infrared light at a specific wavelength. An NDIR sensor comprises an infrared source, a light tube, a bandpass filter, and a detector. The target gas is determined through the filter wavelength choice. For CO2, the most ...

NDIR Gas Sensor for Spatial Monitoring of Carbon Dioxide ...

· comparing NDIR sensors with two commonly applied methods, a Photo-Acoustic Spectroscope (PAS) Gas Monitor and an Open-Path laser (OP-laser). First, calibrations for the NDIR sensors were obtained in the laboratory. Then, the NDIR sensors were placed in a dairy cow barn for comparison with the PAS and OP-laser methods. The main conclusions were: (a) in order to represent the overall barn CO2 ...

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 ...
