An indoor environmental monitoring system for large buildings based on LoRaWAN

Indoor environmental not only educes the overall air quality, but also poses a great threat to people's life safety. Therefore, indoor environmental problems are serious problems. However, at present, the development of monitoring and treatment technology is still immature. Many areas still use manual sampling and laboratory analysis to monitor, which is not only inefficient, but also costly and time consuming. How to use LoRa technology to build indoor environmental monitoring system is a research topic. This paper focuses on the characteristics and advantages of LoRa technology, studies the indoor environment monitoring system based on LoRaWAN, the system architecture. We also try to reduce the air transmission time of RF signals and improve the communication efficiency of the system.
