What Does a CO2 Sensor Actually Do? | GDS Corp

2020-11-06· CO2 sensors use the same operating principle as infrared hydrocarbon detectors. They create a beam of infrared light tuned to a specific frequency that is readily absorbed by CO2 molecules. The primary difference between an infrared CO2 detector and an infrared hydrocarbon detector is the choice of filter and infrared wavelength. Since each molecule of CO2 absorbed some of the infrared …

Complete Gas Sensor Circuit Using Nondispersive Infrared ...

Absorption spectrum of carbon dioxide overlaid with water. If IR light is applied to a dual thermopile detector fitted with a pair of optical filters so that one filter is centered on 4260 nm and the other on 3910 nm, the concentration of carbon dioxide can be measured from the ratios of the two thermopile voltages. The optical filter that resides within the absorption channel serves as the ...

CO2 Sensors for Life Science Incubators |

Carbon Dioxide (CO2) absorbs the wavelength within the infrared portion of the electromagnetic spectrum. An IR emitter then directs the infrared light through a sample of the growth chamber's atmosphere, then through an interferometer filter that isolates the proper wavelength and finally allows the sensor to process the data.

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

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 in the cell can be calculated by ...

Testing the MH-Z19 Infrared CO2 Sensor Module • Circuits

2017-07-11· The non-dispersive infrared (NDIR) carbon dioxide sensors rely on an infrared light source and detector to measure the number of CO 2 molecules in the sample gas between them. Over many years, both the light source and the detector deteriorate, resulting in slightly lower CO 2 molecule counts. To combat sensor drift, during calibration a sensor is exposed to a known gas source, …
