NDIR CO2 Sensor | SSU Ocean Instruments Wiki | Fandom

A nondispersive infrared (NDIR) carbo dioxide (CO2) sensor is commonly used to measure atmospheric CO2 and partial pressure CO2 (pCO2) of seawater. The sensor is spectroscopic. CO2 molecules absorb infrared light. An infrared light is passed through a tube that the gas to be measured. The amount of infrared light absorbed is then measured. Therefore, the absorbance can be used to calculate ...

Complete Gas Sensor Circuit Using Nondispersive Infrared ...

Nondispersive infrared (NDIR) spectroscopy is often used to detect gas and measure the concentration of carbon oxides (for example, carbon monoxide and carbon dioxide). An infrared beam passes through the sampling chamber, and each gas component in the sample absorbs some particular frequency of infrared. By measuring the amount of absorbed infrared at the appropriate frequency, the …

Nondispersive infrared sensor Wikipedia

A nondispersive infrared sensor is a simple spectroscopic sensor often used as a gas detector. It is nondispersive in the fact that no dispersive element is used to separate out the broadband light into a narrow spectrum suitable for gas sensing. The majority of NDIR sensors use a broadband lamp source and an optical filter to select a narrow band spectral region that overlaps with the absorption region of the gas of interest. In this context narrow may be 50300nm bandwidth. Modern NDIR …

How does an NDIR CO2 Sensor Work? |

Small NDIR CO2 sensor breakthrough An engineering breakthrough occurred in 1993 when SenseAir AB patented a design for smallfootprint CO2 sensors . These sensors solved the size problem by using folded optics and metalized molded plastic to reflect the light through a curved shape (referred to as a ''waveguide'') that was longer than the footprint of the sensor module.
