CO2 Dashboards for Ventilation Monitoring in Schools

In February 2020, the CO2 in this particular classroom was reaching peaks of 6,000ppm and for a large portion of the time, the CO2 is greater than 1,500ppm. In October 2020, due to the COVID-19 pandemic, the schools were requested to keep all windows open with the result that the CO2 remained below 1,000ppm on any given day. This presented clear evidence of the impact of ventilation on CO2 in ...
