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

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 use a process called photoionization. Ionization is the changing of an atom’s charge. VOC sensors can ionize particles with ultraviolet light and measure electron levels. These measures allow them to detect toxic or ...

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.
