摘　　要：针对图书馆环境监测的特点,设计了一种基于WiFi的馆舍环境监测系统。传感器节点采用STM32处理器搭载多种环境传感器和ESP8266WiFi模块,模块的AP+STA模式使得节点既可以作为终端,也可以作为路由器。处理器负责将各种传感器检测到的环境参数进行编码,并向WiFi模块发送控制指令和接收数据。通过一种可靠、实用的自动组网方法,实现了环境参数在无线传感器网络中的多跳数据传输。实验表明,系统能够进行馆舍多种环境指标的监测,具有一定的实用价值。According to the characteristics of the library of environmental monitoring,this paper designed a building environment monitoring system based on WiFi.The sensor nodes use the STM32 processor to carry various environmental sensors and ESP8266 WiFi modules.The AP+STA mode of the module not only makes the node as terminal,but also a router.The processor sends control instructions to the WiFi module or receives data from the module and takes charge of encoding the environment parameters detected by various sensors.Through a reliable and practical automatic networking method,the multi hop data transmission of environmental parameters in wireless sensor networks was realized.Experiments show that the system can monitor various environmental indicators and has certain practical value.
