Fireduino与IOT
Fireduino板载WIFI，有完善的网络接口，非常适合需要WIFI联网功能的物联网应用场景。本文结合YEELINK开放IOT平台为例，展示如何快速用Fireduino搭建IOT应用。
Fireduino与YeeLink
YeeLink物联网云平台，可以提供传感器云服务。并通过实时数据处理, 提供安全可靠的状态监控。 YEELINK支持库下载：https://github.com/qinqingege/YeeLinkLib.git 下载后，解压放到arduino的libraries目录。
Fireduino实现远程遥控
如果用Fireduino连接WIFI网络，可以查阅如下WIKI： http://wiki.t-firefly.com/index.php/Fireduino/WiFi_Connect 案例中实现查询YeeLink云设备里开关的状态，当此开关状态为开时，Fireduino打开继电器。 当此开关状态为关时，Fireduino关闭继电器，实现了继电器的远程网络控制。
