前段时间以13.8的优惠价在爱蜥蜴买了群友提到的CEM5855H人体存在传感器（1115H的后继版本吧）规格和1115h一毛一样。
想着把这玩意放在灯罩里是个不错的选择，就开始研究：
家里灯光之前的设置如下
1：灯的驱动是接收红外信号
2：灯的开关已经改成了长按5秒通断电，单击通过万能红外遥控发信号开关灯，所以我家的这个主灯是一直通电的，为这次魔改提供了条件。
研究时拆开了驱动，研究电路发现就是一个小单片机接收红外信号后输出两路pwm信号来控制调光调色。所以我直接拆掉了原来的单片机，引出2根信号线和地线（下图白色线为冷光pwm，黄色为暖光pwm，黑色电源地，橙色5v（未用））
画板时是以ESP32-C3-12F来画的，但事后发现C3在ESPHome下启用不了遥控接收，遂又换回8266 12F，好在它们封装一样.
选择io4，5来做pwm信号，使用两颗7002做电平转换。元器件排成一排。还加上了一个射频模块的位置。
程序方面：
程序还是使用了esphome，这个模块的发货周期很长，等我的模块到祸后，论坛里已经有大佬写出了1115H的在线调参配置 @lannister
因为本来就觉得这俩是一个东西，所以直接Ctrl C+V 了过来，果然是完美可用的。
贴一下我现在的配置，仅供参考

改完后就能直接友好的调色温亮度了

板子先到了，简单焊下
到祸后马上就焊了的电路板（别问我为啥C3开盖了，
因为我买成了2M的版本，开盖是为了换4M的存储）
人体模块就位，在驱动上比划以下
放到驱动上比划以下
把线焊上，扎带伺候
焊上线，咋带捆上
上灯安装，完美
安装回灯上，完美
贴一下没啥技术的原理图
