On the use of CO2 sensors in schools and other indoor ...

Oct 29, 2020 · A CO2 sensor measures the concentration of CO2 in the room, expressed typically in parts per million (ppm). A high CO2 concentration thus indicates poor air quality (1, 4) and the need to ventilate a room (3, 4). The measurement typically occurs continuously over time and requires no supervision. A wide range of CO2 sensors is available on the ...

CO2 Sensors Help Mitigate COVID-19 Risk in Schools ...

In an occupied, well-ventilated room, it is not uncommon for the CO2 level to rise over 1,000 ppm. ASHRAE recommends an 800-1,000 ppm limit for classrooms to ensure overall student health and performance. Note that it isn’t the carbon dioxide itself that is the problem. Humans can still breathe in enclosed areas with CO2 levels approaching 3%.

Altitude Compensation for Gas Sensors - GasLab.com

The pressure temperature compensation for a CO2 sensor calibrated at 400 ppm at sea level at normal temperature would read 400 (623/760) or 332 ppm. A rule of thumb is that the CO2 level at altitude will change about 3% for every 1,000 feet (300 m). At 5,000 feet, that would be 400 ppm less 15%, or about 340 ppm.
