How Do CO2 Sensors Work?

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. For CO2, the most ...

What is NDIR ? | CO2 Sensors | PRODUCTS | Asahi Kasei ...

Photodiode (Infrared sensor of NDIR CO2 sensor) Since the photodiode is a photo type detector, its response speed is overwhelmingly faster (typ. 2μs) than that of a thermal type detector. Therefore, by incorporating this photodiode into a NDIR gas sensor and combining with LED of an infrared light emitter, the power consumption can be reduced to the minimum.

Infrared Sensor Application Note 1 A Background to Gas ...

For NDIR it is usual to regard the sensor as an individual component in the instrument. The key feature is that fixed narrow-band filters are used with individual IR detectors to identify a few gas absorption lines over a limited wavelength range. (This cuts out the dispersive part of a gas spectrometer). Relatively inexpensive sensor components can be resourced and smaller more rugged sensor ...
