ASHRAE Technical FAQ

CO 2 concentrations in outdoor air typically range from 300 to 500 ppm. Thus indoor CO 2 concentrations of 1000 to 1200 ppm in spaces housing sedentary people is an indicator that a substantial majority of visitors entering the space will be satisfied with respect to human bioeffluents (body odor). Note however that CO 2 concentration is not a good indicator of the concentration and occupant ...

CO2 Control In School Classrooms - sensors for commercial ...

carbon dioxide (CO 2) sensors in each zone control the outdoor air damper for that zone. If background (outdoor) CO 2 levels are detected, dampers would remain closed. However, if elevated CO 2 levels occur, indicating occupancy, dampers would open until the CO 2 levels return to background levels. Use of such a demand controlled ventilation ...

Measuring Carbon Dioxide in Outdoor Air |

Carbon dioxide mixes quickly in air, and any CO2 sensor left outdoors will record many different CO2 levels depending on the time of day, the time of year, and even local weather conditions. To solve the problem of measuring CO2 levels on a local level, scientists have developed a 2-pronged approach.

CO2 Sensor Calibration: What You Need to Know |

Where maximum accuracy is less important than cost, a CO2 sensor can be calibrated in fresh air. Instead of calibrating at 0 ppm CO2 (nitrogen), the sensor is calibrated at 400 ppm CO2 (outdoor air is actually between 350 ppm and 480 ppm in normal geographic locations), then 400 ppm is subtracted from the newly calculated offset value. CM-501 Carbon Dioxide Handheld Gas Detector. Fresh air ...
