What is an NDIR Sensor? - Sensors Development

05/12/2018· Sensors continued to get smaller, when in 1993, an engineering breakthrough occurred; SenseAir AB patented a design for CO2 sensors with a small-footprint. As a result, the size problem of the sensors was solved by using folded optics and metalized molded plastic. This was able to reflect the light through a curved shape ('waveguide') that was lengthier than the footprint of the sensor module ...

Measuring Carbon Dioxide (CO ) Using Non-Dispersive ...

In an NDIR sensor measuring CO˚, a Wavelength Filter placed just before the IR Detector only allows that wavelength of IR energy absorbed by CO˚ to pass through. The IR Detector measures the concentration of that wavelength of IR light after it has passed through the sample. Measuring Carbon Dioxide (CO2) Using Non-Dispersive Infared (NDIR) Technology NDIR sensors work using …
