Intelligent Environmental Monitoring System based on LoRa Long Range Technology

The main purpose of this study is to establish an intelligent environmental monitoring system based on Long Range (LoRa) transmission technology with low power consumption to be installed in large-scaled campus with high population density. First of all, sensors at different locations will be configured to provide statistics such as temperature, humidity, suspended particles, carbon monoxide, and carbon dioxide in indoor environment, and temperature, humidity, wind speed, apparent temperature, suspended particles, and ultraviolet light in outdoor environment to serve as the basis for analysis. LoRa 915 MHz serves as the communication protocol of the transmission technology of this system via the transmission module LRM001 developed by Liyatech. An industrial computer is used as the Gateway, and C# Windows Forms is installed for analyzing data from various detection points. The data will be uploaded to Microsoft Azure SQL Server by the unit of hour. In the end the Server end will publish the website via ASP.NET technology and position different detection stations via Google Map API such that users can use the webpage to inquire the trend of environmental quality and the further Big Data analysis.
