[智能家居]: 普通风扇改装智能控制

使用目的：改装家里的老式风扇，接入home-assistant平台，使其支持语音与无人时自动关闭，也可以根据环境温度自动调节风量档位。

1. 使用环境

home-assistant

node-red

esphome

2. 准备材料

esp32 板子

４路继电器

调速电容１只

电阻１只（1～10Ｋ都可以）

3. 硬件接线

忘记拍图了，借网友的图用 下，电阻是串在手动调速按钮上的，作下拉电阻。如果电机是２线的话改接调速电容之后就好。

3. esp32刷入程序

esp32代码，以下x 自己j更改

用可控硅调速，只能按市电频率，没得选

sorrypqa

还是买直流变频风扇吧！按我的使用频率，最高档位38W VS 12W，用个10年8年，连买风扇的钱都能从电费中省回来

双向可控硅移相调压，应该是100Hz。
不过实际上，由于可控硅是半控器件，不应该简单用PWM，而是应该根据过零点延时一定时间（相位），再触发可控硅开通。
如果不对PWM和市电的相位进行同步，理论上会出现一种情况：1%占空比的脉冲正好在过零点触发，导致设备满功率工作。与预期相悖

用的moc3063自带过零.100hz低速还是抖  加电容调速86盒放不下了

这种带过零点检测的光耦，控制交流电的时候，最小单位是一个半波周期，即10ms
我说的移相调压，需要配个过零点检测电路和普通光耦，过零事件发生后，启动计时，延时比如 5ms，触发晶闸管导通（需要普通光耦）这样就是半功率了

过零光耦 当且仅当过零点事件发生时，有输入信号，才能触发导通，其他时间是不能触发的。
机器抖动说明电机功率不稳定可能是因为你的触发脉冲相位处于临界状态，偶尔才能触发光耦
话说100Hz的pwm，竟然能调速？
现在你修改pwm的周期和脉宽，比如周期500ms，占空比以10ms步进依次递增，再看调速性能怎么样
