esp826601s怎么供电

ESP8266 01S 继电器控制 智能灯实现(使用小度音响)
最近研究esp8266,发现可以通过wifi连接物联网云平台实现远程控制,同时也可以加入小度语音DIY简单的智能家居。


前言

本人也是刚接触esp8266纯新手有不对的希望指正。


实物连接方法 :220V接入LED灯,同时并联连220V转5V模块;5V出来给继电器供电,同时并联一个5V转3.3模块给ESP8266 01S供电;ESP8266 01S的URXD引脚也就是GPIO3接继电器控制端,继电器选择常闭端接线高电平触发,控制LED灯亮灭。

补充说明:①市面上的LED灯大多是直接用简单的整流桥芯片搭成,然后串联高亮LED灯,所以继电器选择常闭串入LED灯中,既可以用远程控制,也可以直接用家中的开关控制。
②这里ESP8266供电需要CH_PD和VCC同时加3.3V才能正常启动
