Carbon Dioxide (CO HVAC Basics Honeywell

Rural outdoor CO2 levels are about 350 parts per million (ppm) while urban CO2 levels are considerably higher. OSHA guidelines allow a CO2 air contaminant limit of 5,000 ppm for more than 8 hoursa. In comparison, submarines can reach as high as 7,000 ppm (and on rare occasions even reach a level of 30,000 ppm). Offices typically are 8001200 ppm.


CO2 Sensor Range: PPM and Percentage Compared | …

For smaller volumes, sensor manufacturers and the gas industry measure CO2 and other trace gases in parts per million. For example, % CO2 is equal to 400 parts per million, which is commonly abbreviated as "400 ppm". Indoor Air Quality 10,000ppm CO2. When talking about indoor air, partspermillion makes sense.


Calibration of carbon dioxide sensors

people, animals, and other carbon dioxide sources. Let the sensor carbon dioxide value settle for about 20 minutes. (Since human breathing creates a significant amount of carbon dioxide, for best results leave the sensor during this time.) Then follow the steps above for calibrating the sensor using the outside air carbon dioxide value of 390 ppm.

8/9/2021· For the and CO2 sensors, the data between the TemTop and my two DIY boards is very close (usually < 2% difference, TemTop reads 820 ppm, DIY reads 814 ppm). But note that the SenseAir S8, at least, requires at least a couple weeks to selfcalibrate—it does that I think by trying to get a baseline, and that baseline it calibrates to is somewhere around 440 ppm?
