现学现卖，diy了一个远程浇花的原型

本帖最后由半支红梅于 2022-10-2 13:21 编辑

假期第一天，热得出奇，呆家里折腾出这个”半成品“，期望用它来监控阳台的环境，并可以实现远程浇花。至于今年夏天，我家阳台干死了许多花花，那就是另一个故事了。

APP界面：

使用到的材料：

esp32-c3-12f-kit

5v继电器

bh1750亮度传感器

dht11温湿度传感器

接线：
开发板<====>外设
io19             DHT11 out脚
io18             BH1750 SDA脚
io9                BH1750 SCL脚
io8                继电器 in脚

需要注意的点：
板子上的丝印不一定是正确的！
这个BH1750的sda，scl脚印反了，导致我一度怀疑这个模块坏掉了。
我的这块esp32-c3-12f-kit开发板的丝印居然也是错的！花了不少时间才跳出这个坑。

以下是代码：
