Measuring Carbon Dioxide - The PocketLab

The carbon dioxide (CO2) sensor uses non-dispersive infrared (NDIR) radiation to measure the concentration of CO2 in the air. Background information on carbon dioxide Carbon dioxide circulates naturally in Earth’s atmosphere as part of the carbon cycle (the process in which carbon dioxide is exchanged between the atmosphere, oceans, soil, plants, and animals).

Non-Dispersive Infrared, NDIR, Carbon Dioxide Sensors ...

A basic NDIR sensor consists of an infrared light source, a sample chamber, an infrared filter, and infrared detector. For carbon dioxide sensing, room or duct air is allowed to flow in and out of the sample chamber. Infrared light waves are created by the source and sent through the sample chamber to the detector. As the infrared light passes ...

Top 10 Best CO2 Monitors - MOOZ Reviews

A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas detector. It is non-dispersive in the fact that no dispersive element ( a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing. The majority of NDIR sensors ...

Effects of Temperature and Barometric Pressure on CO2 ...

The most common CO2 sensors are known by the engineering term Non-Dispersive InfraRed, or NDIR. An NDIR CO2 sensor shines infrared light through a gas sample in a sample chamber. Sensitive photo-detectors measure the intensity of the infrared light after it passes through the gas sample. CO2 molecules are opaque to micron infrared light while the rest of the air molecules are not. So the ...
