Design and Implementation of Intelligent Agriculture System Based on LoRa

This paper introduces an intelligent agricultural system based on STM32 as the core control, which realizes data transmission through low-power, long-distance wireless communication technology LoRa, the main node uses Wi-Fi to connect the network, and the application layer uses MQTT protocol for extensive data exchange and management. The hardware uses SPI interface to connect SX1278 chip to complete LoRa communication, and uses solar power supply to meet the needs of agricultural fields. The application layer uses MQTT protocol and communication protocol with custom data format to ensure data consistency and security. The software design includes a Web front end developed by Vue.js to provide a user-friendly interactive experience; The server built by Spring Boot uses MyBatis Plus to operate MySQL database to ensure efficient data storage and retrieval. The smart agriculture system can monitor the growing environment of crops in real time, and control actuators such as low irrigation pumps in real time according to environmental changes, improve agricultural production efficiency and quality, and promote the development of resource-saving agriculture. The system operation shows that the system has good stability and reliability, provides strong support for precision agriculture in modern agriculture, and has high practical value and popularization potential.
