<ul><li style="list-style-type:none;">
<ul><li style="list-style-type:none;">
<ul><li style="list-style-type:none;">
<ul><li>通过语音识别技术，无须联网即可”动动嘴“实现开关机、档位控制。</li>
<li>同时它还保留了实体按键，可以完美改造家里的老风扇。</li>
<li>按键下面搭配了插件的LED灯，可以根据原有的按键高低调整，</li>
<li>3个档位对应实现亮灯，方便识别当前档位；</li>
<li>值得一提的是，通过合理选择LED限流电阻，LED灯在夜晚也并不刺眼，睡觉也不会受到影响。</li>
