Can CO2 sensors be used to assess COVID19 transmission ...
15/1/2021· Measuring indoor carbon dioxide (CO2) concentrations using inexpensive digital sensors (typically less than 500) has been proposed as one way to estimate indoor COVID19 transmission risk, and in fact some jurisdictions have already given directives or guidance regarding the use of CO 2 sensors in settings such as schools.

2/2/2017· 3: Carbon dioxide can kill you. Outside air has usually a CO2 concentration of about 400 ppm and a human breath contains about 30,000 ppm. Carbon dioxide concentrations of more than 20,000 ppm can cause panting. Concentrations above 100,000 ppm of CO2 will cause loss of consciousness and tremors. Values greater than 250,000 ppm have the ...
