The air quality sensor measures carbon dioxide CO2.
High indoor CO2 levels have been shown to lead to reduced cognitive function and productivity, as well as an increased risk of viral infection transmission.
Several clinical studies have shown that human performance and decision-making is impaired as CO2 levels rise from that of fresh air (about 400 ppm). A published study from Harvard University into the effects of CO2 on cognitive ability showed that on average, cognitive abilities decreased by 15% when CO2 levels increased from 600 to 1,000 ppm. Most affected is our ability to use information and make strategic decisions. At CO2 levels of 1,400 ppm, the average decrease was 50% and at 2,500 ppm it was 65%.
Description
Red, Amber, Green indicator
The colour LEDs represents the measured CO2 level:
Green: CO2 is below 950ppm. These are optimal conditions for productivity and represent the lowest viral risk factor.
Amber: CO2 is from 950 to 1400ppm. Productivity may be reduced by up to 15% at 950ppm and 50% at 1400ppm; viral transmission risk is increased.
Red: CO2 is above 1400ppm. As CO2 levels increase productivity will keep decreasing and viral transmission risk will be high. Action should be taken to increase fresh air flow, for example by opening windows, doors, or increasing fresh air ventilation.
Installation guide
The CO2 sensor auto-calibrates, usually within the first 24 hours. Please allow 7 days of continuous operation to make sure the CO2 sensor is calibrated.
