基于STM32F1单片机、ESP8266WIFI模块、DHT11温湿度传感的WIFI网络温湿度传输系统完整工程
功能说明
基于嵌入式的温湿度网络传输系统包含：温湿度采集端与温湿度监控端。
温湿度采集端可实时采集温度与湿度数据，通过WIFI透传技术，将温湿度数据传送到温度监控端。温度监控端实时接收温湿度采集端所发送的温湿度数据，显示在网站上。
注：目前只是在局域网下测试。
温湿度采集端
- 嵌入式STM32微控制器实时读取DHT11温湿度传感器采集的温湿度数据。
- 嵌入式STM32微控制器通过ESP8266WIFI模块连接WIFI。
- 通过TCP协议连接到电脑服务器，将温湿度数据传输到服务器。
温湿度监控端
- 通过建立Serversocket监听指定端口，获得温湿度采集端的温湿度数据。
- 将获取的数据通过WebSocket建立与客户端web页面的实时连接，将数据传送到web页面
- web页面可实时显示温湿度数据、查询温湿度数据、将数值图形化用动态柱形图的形式展现。
