Our partner CEAM (www.ceam.es) is part of the initiative AIREAMOS (www.aireamos.org) to reduce the risk of COVID-19 infection by promoting ventilation and monitoring of CO2 indoors, especially in schools and crowded spaces.
CEAM has participated in a document summarizing the tests of commercial CO2 sensors (Villanueva et al.) as a guide for interested users. These users can be the general public, but also schools, restaurants, health centres, etc.
In this framework, from 1st to 5th February, the CEAM team has hosted an intercomparison campaign at the EUPHORE chamber, to test and calibrate different models of CO2 sensors. The call invited anyone owning a commercially available CO2, as well as models which are still being developed.
The results of the campaign will soon be made available.
