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 commonly used wavelength is µm. This …

Measuring Carbon Dioxide (CO ) Using NonDispersive ...

Similarly, an NDIR sensor works via spectroscopy in that an IR lamp emits a beam of IR light containing a wide energy spectrum (~900nm100,000 nm) which is measured by the IR detector at the other end of a chamber. When a sample of gas is pumped into the Gas Sample Chamber, certain gases such as CO˚, act as a ˛lter absorbing a speci˛c wavelength of energy within the IR spectrum. Other gases ...

How do the sensor and CO2 sensor work? | AirVisual ...

How does the IR CO2 sensor work? The CO2 censor is composed of an infrared (IR) lamp, a reflective gas cell, and IR filtered detectors. The IR lamp sends waves of light towards the IR filtered detectors, which can measure how much IR light reach them. While the IR light goes through the cell, CO2 modules absorb lights of certain wavelength (shown in the graph). Thus, the number of CO2 modules ...

Carbon Dioxide Sensor Sensor Technology

The carbon dioxide gas sensor measures gaseous carbon dioxide levels by detecting the quantity of IR radiation absorbed by carbon dioxide molecules. The sensor employs a hot metal filament that acts as an IR source to generate IR radiation. The IR source is located at one end of a sensor tube, and another end is provided with an IR sensor.

How does an NDIR CO2 Sensor Work? |

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 detector. The IR light detector measures the amount of IR light that passes through the optical filter.
