Abstract: To promote rural revitalization in new era, an integrated information acquisition system based on LoRa technology for agricultural informatization applications has been researched and designed．System employed an STM32 microcontroller, 5G wireless data collection and transmission module, master-slave distributed LoRa node modules, various sensors, a solar power supply system, public and private cloud platform, and intelligent mobile terminals for data visualization．Master-slave operation process emplyed a master-initiated query method, wherein master sent query frame to each slave．Slave compared recieved query frames against their local setting values, if consistent, data collected bt sensors was packaged and transmitted to master．Host then packaged slave data from multiple nodes and sent it to cloud platform through 5G modules．Intelligent mobile terminals could vies real-time data from cloud platform．This system effectively collected and stored data on soil elements, air quality, meteorological information, and other parameters, with a simple structure．It not only enhanced agricultural production efficiency and accuracy, but also reduced operating costs and energy consumption, providing strong support for agricultural informatization and green agricultural development．
