zigbee终端节点实现协调器控制同步休眠同步唤醒，未收到指令时异步休眠同步唤醒。新加入节点自动同步。-Zigbee coordinator control terminal node dormancy synchronization, are not yet received instructions asynchronous awaken dormant synchronization.New to the automatic synchronization.

读取DHT11值，休眠，回传给终端节点。(Reads the DHT11 value, hibernate, and returns to the terminal node.)
