CO2 Sensor Measurement Range, Accuracy and Precision ...

NDIR CO2 sensors take a new reading anywhere from 20 times a second to once every 30 seconds. As each reading is taken the sensor's on-board software takes into account all the previous measurements and report the average. This solves the problem of precision. If you want a more precise CO2 reading, look for a sensor with a higher frequency of measurements. Assuming the sensor is properly ...

Basic Principle of NDIR Gas Detection - Heimann Sensor

The picture below illustrates the principle using the example of a NDIR CO2 sensor: ... The low cost HSL Series has two major limitations compared to the high performance source. First is speed, as it as much higher time constants for the heating and cooling of the filament. Second is emission of IR radiation. The low cost IR source has a blub made of quartz glass. This glass blub absorbs more ...

Signal conditioning for NDIR sensor - Application note

Non dispersive infrared (NDIR) is a quite old technology as the first research was carried out in 1930’s in the USA by the department of defense. The commercialization of NDIR started in the 50’s without never reaching big volumes mainly due to its size and output drift over the time. This technology finally reached its full potential in 2010 when new technology of NDIR appeared allowing ...

How does an NDIR CO2 Sensor Work? |

The band of infrared radiation is very close to the absorption band of CO2. As a result, the amount of light radiation that is absorbed by the CO2 molecules is proportional to the amount of carbon dioxide in the gas sample. However, since low levels of CO2 do not absorb much light, a long tube is needed before the effect can be measured.

Nondispersive infrared sensor - Wikipedia

NDIR sensors for carbon dioxide are often encountered in heating, ventilation, and air conditioning (HVAC) units. Configurations with multiple filters, either on individual sensors or on a rotating wheel, allow simultaneous measurement at several chosen wavelengths. Fourier transform infrared spectroscopy (FTIR), a more complex technology, scans a wide part of the spectrum, measuring many ...

Complete Gas Sensor Circuit Using Nondispersive Infrared ...

Nondispersive infrared (NDIR) spectroscopy is often used to detect gas and measure the concentration of carbon oxides (for example, carbon monoxide and carbon dioxide). An infrared beam passes through the sampling chamber, and each gas component in the sample absorbs some particular frequency of infrared. By measuring the amount of absorbed infrared at the appropriate frequency, the ...
