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.

The CO2 Analyser is a Analytical instrument that measures the concentration of CO2 gas in the process. The CO2 Analyzer use multi-component analysis by using Non Dispersive Infrared (NDIR) sensor technology for consistent, precise process gas measurement.
A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas 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 basic measurement principle is called nondispersive infrared (NDIR) gas detection, which is based on the absorption of infrared radiation at certain gas specific wavelengths in accordance with the Beer-Lambert law. The most common gases that are measured with this NDIR principle are carbon dioxide (CO2), methane (CH4) and hydrocarbons (HC).
But Co2 only consists of % of the atmosphere meaning; it’s a trace gas that’s quite difficult to detect. The Atlas Scientific EZO-CO2 sensor is a compact Non-Dispersive Infrared (NDIR) sensor that gets right to the point, giving you the Co2 readings in ppm.
The circuit shown in Figure 1 is a complete thermopile-based gas sensor using the NDIR principle. This circuit is optimized for CO2 sensing, but can also accurately measure the concentration of a large number of gases by using thermopiles with different optical filters. The printed circuit board (PCB) is designed in an Arduino shield form ...
CO 2 transmitters are available in different enclosures. These NDIR CO 2 sensors measure temperature, relative humidity and CO dioxide or CO 2 is a result of human metabolism. Moderate to high levels of CO 2 can cause headaches and fatigue. To prevent or reduce high concentrations of carbon dioxide in a building or room, fresh air should be supplied to the room.
