CO2 Sensor Location: Where to Mount Your CO2 IAQ Monitor ...

Indoor Air Quality: In most homes or offices, wall-mounted CO2 level transmitters are used to monitor carbon dioxide levels as they would be experienced by occupants. They can be located at the same height (48 inches or 122cm is standard) and on the same wall as you would mount a thermostat. Like a thermostat, they should not be near outside doors or windows that can make the space appear to …

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.

HVAC Sensors – CO2 And On-Demand Ventilation | MicroMetl ...

CO2 sensors According to a recent study by Harvard School of Public Health, high CO2 levels in a building can have a direct negative impact on thinking and decision making. CO2 sensors can detect the levels of CO2 gas in a space, which can increase to undesirable levels as occupancy increases. When the threshold is reached, a smart HVAC system can increase levels of fresh air supplied to the space. …

The role of sensors in modern HVAC systems

Similarly, air quality sensors (CO2, TVOC, CO, NO2 etc) are also often combined with temperature and humidity sensors into a single device. The energy efficiency of modern HVAC system is greatly enhanced by the proper communication between sensors, controllers and HVAC components, for example fans or dampers. As a result, it is of great importance that the whole systems communicates …
