How does an NDIR CO2 Sensor Work? |

How does an NDIR CO2 Sensor Work? January 05, 2021 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.

COVER STORY 2 Sensor Helps to Reduce the Risk of Covid-19 ...

HVAC systems use the values to adjust the air mixture in the room automatically to that of the outside air according to the targeted appli- cation requirements. This keeps indoor CO 2 concentration at a specific value — for instance, below 1,000 ppm according to the ASHRAE standard on ventilation and acceptable indoor air quality in residential buildings. Given the benefits of CO 2 sensing ...

5 HVAC sensors you need to know about - Primex HVAC Venting

The basic IAQ sensor is a carbon sensor, which detects carbon levels in the air. Carbon levels are an indicator of air circulation, and poor air circulation increases the chances that other contaminants could be present. Carbon dioxide sensors use either infrared light or a chemical process to measure levels of CO2. Sensors are also used to detect volatile organic compounds (VOCs). VOC sensors ...

Why measure CO2 in HVAC applications? |

Instead of constantly providing fresh air, buildings used carbon dioxide sensors to “sense” when the buildings were occupied. When enough people enter a room, the CO2 level rises because of the CO2 from their exhaled breath, and the HVAC system begins to bring in the fresh air. When the people leave, the CO2 level drops because they are no longer breathing in the room, and the fresh air dampers close.
