CO2 Sensor Calibration: What You Need to Know |

Most of our CO2 products use nondispersive infrared (NDIR) carbon dioxide sensors. These rely on an infrared light source and detector to measure the number of CO2 molecules in the sample gas between them. Over many years, both the light source and the detector deteriorate, resulting in slightly lower CO2 molecule counts.

Complete Gas Sensor Circuit Using Nondispersive Infrared ...

The maximum NDIR chop frequency is 5 Hz, and the minimum half cycle pulse width is therefore 100 ms. The settling time to 22 bits is approximately × the minimum chop pulse width. The AD8629 has a Hz to 10 Hz input voltage noise of μV pp. Ignoring the sensor voltage noise and the AD8629 current noise, a 1 mV pp signal output from the thermopile yields a signaltonoise ratio ...

Carbon dioxide sensor Wikipedia

NDIR sensors are spectroscopic sensors to detect CO 2 in a gaseous environment by its characteristic absorption. The key components are an infrared source, a light tube, an interference (wavelength) filter, and an infrared detector. The gas is pumped or diffuses into the light tube, and the electronics measure the absorption of the characteristic wavelength of light.

Basic Principle of NDIR Gas Detection Heimann Sensor

The basic measurement principle is called nondispersive infrared (NDIR) gas detection, which is based on the absorption of infrared radiation at certain gas specific wavelengths in accordance with the BeerLambert law. The most common gases that are measured with this NDIR principle are carbon dioxide (CO2), methane (CH4) and hydrocarbons (HC).
