Design of Wireless Remote Agricultural Monitoring System Based on Embedded LoRa Technology
A wireless remote monitoring system based on embedded LoRa technology was designed to meet the needs of large-scale coverage,long-distance transmission,and low-power operation in the field of agricultural monitoring.Using STM32 as the core controller,a flexible and self-organizing wireless LoRa network was constructed between monitoring nodes and gateways through LoRa modules to achieve real-time collection of agricultural environmental parameters.After processing and packaging,the collected data is transmitted to the server through a Wi-Fi module and visualized on the upper computer.In addition,when the data exceeds the preset threshold,the relay can be automatically turned on to control the actuator.The test results have verified the stability of LoRa network in long-distance communication and the effectiveness of real-time monitoring,effectively improving agricultural efficiency and the level of intelligence.
