听说标题长了好。。。够长吧。。。。
esp8266 NTP了时间给DS1307 然后读DS1307的时间给TM1637
然后采集DHT11和BMP180的数据通过MQTT协议发给 Domoticz 服务器做展示 只是做个表的话放着感觉有点浪费 于是顺便采集一下环境情况了
至于外观么 就是这样的。。。外面我也套了一个 ardunino的亚克力壳 算是抄袭坛子里一位朋友的创意了
联接也简单 I2C 的 BMP180 DS1307
自己联的TM1637 和 DHT11

上源码吧
能运行，但是就是写的不好看，反正是自己玩。。。也不优化和美观了，能给各位提供点灵感就好了。。。。

为何我传PYTHON的代码 使用代码那个总是没了缩进。。。又加了个附加 内容一样的
