infrared co2 sensor principle

Infrared Carbon Dioxide Sensors -

Principle of carbon dioxide detection. Two optical filters are mounted on the detector surface. One filter is chosen to pass the infrared light specific to carbon dioxide (measurement filter). The second filter is a reference filter. Light at a wavelength that is not absorbed by carbon dioxide passes through the reference filter. The difference in amount of light between the two filters ...

CO2 Sensors: definition, types, and how to choose? - Renke

2021-08-02· The non-dispersive infrared carbon dioxide sensor is made based on the working principle that the absorption spectrum of gas varies with different substances. The carbon dioxide sensor element controls the internal infrared lamp to emit infrared light of a fixed band through the drive circuit. After the absorption of the gas to be measured, the amplitude of the infrared light changes, …

Nondispersive infrared sensor - Wikipedia

Principle. The main components of an NDIR sensor are an infrared (IR) source (lamp), a sample chamber or light tube, a light filter and an infrared detector. The IR light is directed through the sample chamber towards the detector. In parallel there is another chamber with an enclosed reference gas, typically nitrogen. The gas in the sample chamber causes absorption of specific wavelengths ...

How does an NDIR CO2 Sensor Work? |

Like every IR gas sensor, the analyzer at Mauna Loa used the same basic principle for measuring CO2. It has an infrared light radiation source at one end of a gas sample tube and an IR detector at the other. The band of infrared radiation is very close to the absorption band of CO2.

Low Cost IR CO2 Sensors -

This CO2 sensor module is designed to monitor 0-5,000ppm carbon dioxide levels using a dual beam light source and NDIR sensing technologies. By using the dual-infrared source principle, the CU-1107 sensor compensates for long-term drifts by design. Dual beam detection allows for superior stability and better accuracy over the predicted 10 year lifespan of the sensor. It can achieve equivalent ...

Principle of Operation The infrared detection principle incorporates only a small portion of the very wide electromagnetic spectrum. The portion used is that which we can feel as heat. This is the region close to the visible region of the spectrum to which our eyes are sensitive. Electromagnetic radia-tion travels at close to 3 x 108 m/sec and has a wave-like profile.
