Description

technical field [0001] The invention belongs to the field of communication technology, and in particular relates to an energy-saving and environment-friendly intelligent indoor environment monitoring device. Background technique [0002] With the continuous development of urban industrialization and the continuous evolution of modernization, air pollution has appeared in large and medium-sized cities at home and abroad. Especially since the winter of 2012, smog weather with PM2.5 as the main pollutant has appeared in most parts of North China. Different from the relatively large particles in the air, the particle diameter is small, and there are some toxic organic and inorganic substances on the surface, which can stay in the air for a long time, and may be blown to distant places with the wind. Therefore, it has a great impact on people's lives and endangers people's health. As China's economic development is getting better and better, people's living standards are also i...
