Abstract:
本文提出一种基于低功耗广域网LoRa无线网络技术的物联网水质监测系统。以STM32F103ZET6作为水质采集终端的主控制器，SX1278芯片作为通信模块，构建星型拓扑网络架构，实现了多节点水体温度、pH值与总溶解固体量(TDS)等水质参数的远程采集。LoRa网关通过TCP/IP协议将水质数据传输到服务器的MySQL数据库，采用Grafana实时监测数据库各节点水质参数。
In this paper, an IoT water quality monitoring system based on low-power WIDE LoRa wireless network technology is proposed. The STM32F103ZET6 as the main controller of the water quality collection terminal and the SX1278 chip as the communication module, the star topology network architecture is constructed, which realizes the remote collection of water quality parameters such as multi-node water temperature, pH value and total dissolved solids (TDS). The LoRa gateway transmits water quality data to the server’s MySQL database through TCP/IP protocol. The system uses Grafana to monitor the water quality parameters of each node in the database in real time.
