Description
Technical Field

Background
In modern society, the outdoor environment is more and more severe due to the damage of human beings to the nature, and the indoor environment is more and more not up to the standard of healthy living due to indoor decoration. The lung diseases can be caused in outdoor haze environment for a long time, and the leukemia can be induced in indoor high-concentration formaldehyde environment for a long time, especially for growing fetuses and infants. This has led to increased interest and increased demand for indoor and outdoor air quality monitoring.
