| Summary: | This paper addresses the current limitations of environmental monitoring methods in China, including insufficient coverage and data latency, by proposing an IoT-based environmental monitoring system. The system uses STM32 as the central controller to collect environmental parameters such as air temperature/humidity, atmospheric CO₂ concentration, water dissolved oxygen concentration, and soil conductivity in the Yellow River Delta region. Data is transmitted to the EMQX cloud platform via a 4G module using the MQTT protocol for efficient communication. The system features real-time monitoring, data storage, visualization, and early warning capabilities. Experimental results demonstrate stable operation, high data accuracy, and strong scalability, providing robust support for environmental governance and potential applications in broader monitoring scenarios. |
