Increasingly efficient building insulation can help to mitigate the effects of climate change, but heavily insulated buildings are not always good for human health. Poor ventilation can result in lower oxygen levels and a build-up of carbon dioxide (CO2). Even moderate levels of CO2 can have a negative impact on health and productivity. Already at 1000 ppm, people begin to experience drowsiness and have difficulty concentrating. Consequently, there is a growing demand for smart indoor air quality sensors that can “smell” rising levels of CO2 and either alert the user or trigger a system response.
Key Features
- Operating range: 0 ppm to 10000 ppm
- Accuracy: ± (30 ppm +3%) of reading between 400 ppm and 5000 ppm
