Figure 1: A basic infrared CO2 sensor structure. The incandescent bulb generates light. Gas enters the chamber and interacts with the light. An interference filter blocks all light except at wavelength µm, where CO2 gas absorbs. That absorbance is then detected and processed to signal downstream effects.
With the recent pandemic, awareness of indoor air quality is rising, making accurate, affordable monitoring solutions like the XENSIV™ PAS CO2 sensor more important than ever. It has been shown that a correlation exists between the concentration of CO 2 and aerosols, one of the transmission pathways of viruses (like COVID-19 or influenza).
Those lamps also have wide wavelength length which covers from the visible light region to the near-infrared and mid-infrared regions. In particular, relatively large infrared output can be obtained at 3 µm to 5 µm wavelength which is required for CO2 sensors. Therefore, even when it is used for a dual-wavelength method sensor (a system which uses not only an absorption wavelength but also a ...
The more CO2 in the gas sample the less light passes through, making the difference of allowing the circuits to calculate the accurate percentage of carbon dioxide. Why choose an Infrared IR CO2 Sensor? For those technicians working in incubation or microbiology labs, making selecting the proper sensing technology can be a difficult task. While ...
The infrared sensor offered by Systech Illinois in the carbon dioxide detection equipment is a single beam, dual wavelength temperature compensated sensor. It incorporates an infrared lamp light source and pyroelectric detector. The gas flows through a sample cell with sapphire windows. Principle of carbon dioxide detection. Two optical filters ...

· Infrared lit sensors can spot carbon-dioxide. LEDs can shed infrared light on low cost, long lifetime sensors to monitor carbon dioxide levels in buildings, suggests Ralph Weir. GSS invested in its own epitaxy machines to manufacture mid-range IR LEDs. To most people carbon dioxide (CO2) is a ‘greenhouse gas’, but not directly harmful to ...

Replacing the incandescent light bulb with microglow technology increases the sensor’s operational lifetime by 50%, while power consumption is only 25% that of traditional infrared sources. The high amount of heat generated by incandescent light bulbs limits their applicability in multiparameter transmitters measuring not only CO 2,
NDIR is an industry term for " nondispersive infrared ", and is the most common type of sensor used to measure carbon dioxide, or CO2. An infrared (IR) lamp directs waves of light through a tube filled with a sample of air toward an optical filter in front of an IR light …
· IR sensors, on the other hand, operate on the theory that light is absorbed by gases at specific frequencies. For instance, light is absorbed by CO2 at μm, within the IR band of the electromagnetic spectrum. The sensor measures the IR light directed at the CO2 gas. Other wavelengths are prevented from hitting the sensor via a filter.

Chapter 5 Infrared Gas Sensors Frequency: Number of waves per second passing through a point. An electromagnetic wave travels at the speed of light which is 300 million meters per sec-ond, or 3 x 10 8 m/sec. Therefore, the frequency is the speed of light divided by the wavelength, and is ex-pressed as the number of waves per second, or hertz (Hz).
· The main components of an NDIR sensor are an infrared source (lamp), a sample chamber or light tube, a light filter and an infrared detector. The IR light is directed through the sample chamber towards the detector. In parallel there is another chamber with an enclosed reference gas, typically nitrogen. The gas in the sample chamber causes absorption of specific wavelengths …
LMP91051 NDIR CO2 Gas Detection System ... is based on the principle that gas molecules absorb IR light and absorption of a certain gas occurs at a specific wavelength. Typically, a thermopile with a built-infilter is used to detect the amount of a specific gas. For instance, since CO2 has a strong absorbance at a wavelength of µm, a band-passfilter is used to remove all light outside of ...
If IR light is applied to a dual thermopile detector fitted with a pair of optical filters so that one filter is centered on 4260 nm and the other on 3910 nm, the concentration of carbon dioxide can be measured from the ratios of the two thermopile voltages. The optical filter that resides within the absorption channel serves as the detection channel and the optical filter that resides outside ...
The IR light is directed through the NDIR sample chamber towards the detector. The detector has an optical filter in front of it that eliminates all light except the wavelength that the selected gas molecules can absorb. Other gas molecules do not absorb light at this wavelength, and do not affect the amount of light reaching the detector.
