What is NDIR? | Oshino Lamps Ltd.

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 ...

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).

Testing the MH-Z19 Infrared CO2 Sensor Module • Circuits

· 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 -

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 ...

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.
