Carbon dioxide (CO2) sensors and monitoring devices are offered in many different ranges, from 0 ppm (parts per million) to 100% CO2. Selecting the sensor or monitor with the correct range of CO2 to be measured for your application is important.

Earlier onset of exercise-induced angina (HbCO 4.96%) (WHO 13: 35 ppm. Maximum allowable outdoor concentration for one-hour period in any year, EPA (ASHRAE) 40 ppm. Some residential detectors might give a low-level alarm after several hours exposure.
>40,000 ppm
Carbon dioxide CO2 levels outdoors near ground level are typically 300 ppm to 400 ppm or 0.03% to 0.040% in concentration. Carbon dioxide CO2 levels indoors in occupied buildings are typically around 600 ppm to 800 ppm or 0.06% to 0.08% in concentration. The UK’s Met Office predicts monthly concentrations of carbon dioxide, the main driver of rising temperatures and the climate crisis, will peak in 2021 at about 419.5 ppm.

micro atm pCO2 is partial pressure of CO2. For gaseous species, the mole fraction is represented in units of ppm (for e.g. moles of CO2 per million parts of air). Now assuming ideal gas equation
Higher concentrations were achieved by injecting ultrapure CO2. Ventilation Dec 1, 2015 Carbon dioxide pollution is the primary reason the Earth is warming. CO2 is measured in parts per million, a tiny increment with huge effects. Feb 25, 2014 CO2 concentration in ambient air ranges from 300-500 parts per million (ppm), with a global atmospheric average of about 400 ppm.
