制作了一个 温湿度 空气质量检测仪
本帖最后由 flashtttt 于 2019-12-5 17:52 编辑本作品完全开源 禁止用于商业用途作品具有温湿度 空气质量可视化功能 通过下方的RGB灯带显示。
主控选用esp-8266用到的模块有 温湿度传感器-dht11人体红外感应模块HC-sr505 空气质量传感器ZP01模块
电路板使用立创eda绘制 具体可查看https://oshwhub.com/flashtttt/wu-lian-wang-kong-qi-wen-shi-du-jian-ce-yi

app组件创建：
作品外壳是3d打印 这里附上3d模型文件
楼主的3d建模很烂 所以 大家将就用一下0.0
作品前面的olde是1.3寸的oled 不要用0.96寸 不然还得修改程序，外壳也安装不上
作品顶用半透明的材料去打建议模块的连接使用xh2.54间距连接器和排线连接 不要使用杜邦线 容易接触不良 也不方便。同时注意正负极 一旦接反就GG了。
具体的安装过程就不放了 或者日后有时间再做一期帖子，有问题的话大家下方留言。
好大的个头 OLED U8G2库怎么添加进去一直是无效库，求救
