Sensor de CO2 HVAC.

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.

CO2 Sensors vs. VOC Sensors for IAQ What''s the ...

CO2 sensing technology by IR (infrared) is stable and is not subject to the shortterm, random drift found in air quality sensors. Most IR carbon dioxide sensors only measure CO2. A CO2 sensor is designed to control the ventilation rate in occupied spaces. People are the principal source of CO2 in indoor air.
