What every architect needs to know about air and SarsCov2

2021-02-02· People produce CO2 when they exhale, and CO2 can be accurately measured with a low-cost sensor. For about $300, a portable CO2 monitor provides an instant readout of CO2 in any space, be it a bus, car, school, hospital, classroom or bedroom. I like the Aranet4 because after calibration, it has low power draw, samples every 5 minutes and is ...

Indoor CO2 sensors for COVID-19 risk mitigation: Current ...

2021-05-18· 2021-05-18· Does a high CO 2 level mean that COVID risk is high? No. Being exposed to high CO 2 levels does not mean you will contract COVID-19, and having low CO 2 levels does not mean that you cannot contract COVID-19. Although CO 2 has been proposed a proxy for COVID-19 risk, 19 the readout on a CO 2 sensor is not a direct indicator of COVID-19 risk. 13 The risk of COVID-19 …

Identifying poorly ventilated areas and using CO2 monitors

People exhale carbon dioxide (CO2) when they breathe out. If there is a build-up of CO2 in an area it can indicate that ventilation needs improving. Although CO2 levels are not a direct measure of possible exposure to COVID-19, checking levels using a monitor can help you identify poorly ventilated areas. Types of CO2 monitor to use. There are many different types of CO2 monitors available ...
