KOMPAS.com – Chilean scientists are again using a carbon dioxide (CO2) detector monitor model to warn and stop the risk of spreading the coronavirus that causes Covid-19 indoors.
Reported from Reuters, Thursday (24/6/2021), this prototype measures air pollution in a room with people in it.
The tool will detect the corona virus if someone is infected, which is known through exhaled steam.
These devices that have not yet been sold, will upload to the cloud and issue an audio warning if ventilation is inadequate, which may result in transmission or transmission of Covid-19.

The monitor to detect the spread of the corona virus, developed by the Center for Mathematical Modeling and the Center of Excellence in Astrophysics and Technologies Related University of Chile, has been tested on campuses at universities in this South American country.
“If you’re in a place that doesn’t have combustion, the only source of CO2 is humans,” says Ricardo Finger, an electrical engineer at the University of Chile.
“But if you measure the amount of CO2 in the air, you can estimate how much air one person has inhaled that another person has inhaled.”
Finger further explained that the concentration of carbon dioxide, as well as temperature and humidity levels, which are transmitted by radio signals to the control panel, can monitor dozens of sensors simultaneously.

“CO2 sensors have been around for a long time, but the difference is that they were not previously considered to deal with coronavirus transmission,” said Finger.
“This focus has been given mainly on surfaces, on contact, in hand washing and it has been ruled out that transmission can occur purely through the air,” he explained.
As Chile enters winter from the Southern Hemisphere, people spend more and more time indoors with their windows and doors closed.
Facing this condition, health authorities are competing with Covid-19 vaccinations to avoid a spike in Covid-19 cases and the spread of the corona virus.
