With the improvement of people's living standards and the popularization of the Internet, indoor activities have become a major feature of contemporary people's lives, which results in the great demand for accurate and intelligent real-time monitoring of indoor environment. However, there are some defects, such as the market of indoor air monitoring in the monitoring industry is small, and the popularization and popularization of monitoring products are low. Therefore, mainly starting from the current market situation of indoor air monitoring, this paper analyses the necessity of promoting the marketization of indoor air monitoring, and studies the related technologies of current indoor air data, such as acquisition, processing and analysis. Then we expounds the operability of popularizing indoor air monitoring system, and put forward for how to develop the room in the Internet era. Opinions and countermeasures in the internal air monitoring.

The title compound, [MnCl2(C24H20N6)], has been synthesized and characterized based on the multifunctional ligand 2,5-bis(2,2'-bipyridyl-6-yl)-3,4-diazahexa-2,4-diene (L). The Mn(II) centre is five-coordinate with an approximately square-pyramidal geometry. The L ligand acts as a tridendate chelating ligand. The mononuclear molecules are bridged into a one-dimensional chain by two C-H···Cl hydrogen bonds. These chains are assembled into a two-dimensional layer through π-π stacking interactions between adjacent uncoordinated bipyridyl groups. Furthermore, a three-dimensional supramolecular framework is attained through π-π stacking interactions between adjacent coordinated bipyridyl groups.
