把一个废柴插座转眼变身远程控制智能插座
本帖最后由 IOT专业户 于 2019-12-4 17:47 编辑把一个废柴插座转眼变身远程控制智能插座该项目主要基于Arduino D1 mini（wemos）模块和MQTT协议和移动Onenet物联网云平台实现远程控制1、选插座一定要选择这种花里胡哨，内部空间大的，这样便于后期改造https://www.arduino.cn/forum.php?mod=image&aid=59657&size=300x300&key=19046f633bb68183&nocache=yes&type=fixnone 2、线路改造，可以看到进来两根线一根线经过开关，结构简单粗暴，便于改造https://www.arduino.cn/forum.php?mod=image&aid=59658&size=300x300&key=9e4ccebfe829e1a4&nocache=yes&type=fixnone
https://www.arduino.cn/forum.php?mod=image&aid=59663&size=300x300&key=55f97b960621aa07&nocache=yes&type=fixnone3、寻找合适的安装位置，我这里放了两个3.3V的一路继电器，和一个Arduino D1 MINI这种某宝一大堆，（本来准备把那个四路遥控器也安装上去，但是无奈这个信号输出是5V的所以不能用，用三极管改造一上午居然还给我搞坏了，气死直接丢垃圾桶）https://www.arduino.cn/forum.php?mod=image&aid=59664&size=300x300&key=f61851d6ee136838&nocache=yes&type=fixnone图中画圈区域就是改造区域，选用这个接线板的好处就是板载自带5V电源，所以就不需要自己再接220VAC转5V模块了，直接上电测出5V电源连接到Arduino上的5V个GND即可，完成本项目所需的电源供应。因为没用到四路遥控模块所以这里连线非常简单，就是继电器信号线连接到D1和D2上即可。
4、打上热熔胶，固定住元器件，（注意：热熔胶在高温下是导电的，如果你的插座比较好或者后期要用到大功率电器上，那么尽量别用热熔胶，选用其它胶水比如502这种），编写程序，烧写代码，把螺丝拧上即可。5、测试——效果完美，达到预期效果 https://www.arduino.cn/forum.php?mod=image&aid=59659&size=300x300&key=9af11eb241acc87e&nocache=yes&type=fixnone
https://www.arduino.cn/forum.php?mod=image&aid=59660&size=300x300&key=d994d7f2f57232cc&nocache=yes&type=fixnone
https://www.arduino.cn/forum.php?mod=image&aid=59661&size=300x300&key=b3aa81ff586b07fc&nocache=yes&type=fixnone
https://www.arduino.cn/forum.php?mod=image&aid=59662&size=300x300&key=2aa98bb53fb06e42&nocache=yes&type=fixnone代码：由于部分代码涉及隐私信息已用XXXXX代替，写程序的时候注意修改即可
