Design of Remote Monitoring System Based on STM32F407 Microcontroller

This paper studied an integrated system to accomplish a real-time remote monitor function, which is based on STM32F407 embedded development board, through the Reduced Media Independent Interface (RMII), Flexible Static Memory Controller (FSMC) interface and web development, etc. The STM32F407 embedded development board is a core controller in the system and it is connected to Internet to realize the function of web server with Light Weight IP (LWIP) communication protocol. The value of various sensors can be transmitted to web server in real time with Server Side Include (SSI) instruction, and any device connected to Wi-Fi can realize the remote monitoring function through the router. Experiments are conducted with DS18B20 temperature sensor and the first channel of Analog-to-Digital Converter (ADC1) in STM32F407 to verify the effectiveness of the system. The results show that the embedded remote monitoring system works effectively. The system is convenient and practical in many industries.
