Intelligent Environment Monitoring System Based On Wireless Communication

With the continuous development of mobile Internet, mobile terminal user is rapid growth. And under the age of the Internet, people demand for the quality of life is also changing. However, urban integration steps forward, and the rapid development of modern industry for people bring benefits at the same time, also produced some environmental problems. So for the most basic home environment in which people live have gradually been attention.In environmental indicators, involves some basic parameters, and some of the household environment safety index is associated with people. In this thesis, considering the above issues, based on a Wi-Fi wireless communications, embedded technology designed and implemented a collection of things general circuit board,and to have now popular Android handheld devices designed a development performance is strong, easy iteration, live entertainment set integrated application software programs.In order to enhance the system’s generality, this system underlying the Internet of things floor reserved the expansion of the basic interface, and to use the Cortex_M3 as the kernel of STM32F103 as circuit board at the bottom of the main chip, using some fast networking development of science and technology of USR-Wi-Fi232-T Wi-Fi as the wireless transmission of data through a communication module, using the DHT11 with better performance, GY301, MQ-5, HOCO sensor modules as data acquisition terminal. Application software runs in smart handheld devices, with Android software development using Eclipse3.7 to write JAVA code. This application USES the modular framework for development, this for later maintenance, iterations, and secondary development. Armed with the data storage using SQLite database. The underlying data collection, upload, handheld device through the Wi-Fi data read, and saved to the database, the user can see on a regular basis, and can carry out simple data analysis, according to the reasonable Suggestions and safe warning.This system is in combination with laboratory environment to collect data on the accuracy of the general circuit board, the Wi-Fi data communication reliability and the stability of the Android application was tested, the results show that the system can meet the environmental monitoring and its practical value, and can the owning environment under the premise of some basic data processing, warm prompt for users.
