本人是完全不懂C语言，大部分都是借鉴各位大佬的，没有时间和精力去学习C语言，能达到自己的使用效果就好。非常感谢各位大佬。上面是APP界面，下面是代码。错误地方多多指正新手

兄弟，需要哪些硬件设备之类的能否罗列一下出来，感谢

我用的是下面的设备
安信可ESP32 NodeMCU-32S CH340
土壤湿度传感器：电容式土壤湿度传感器模块 Molsture Sensor V1.2
温湿度传感器：DHT11
继电器；可以调高低电平触发的1路继电器
水泵；直流电机小潜水泵 2.5V-6V
电源供电是直接用手机充电器供电的，水泵的电源是单独的一个手机充电器供电。

天气及空气质量是用的Blinker请求返回的数据
继电器信号脚插在 esp32的 12脚
土壤湿度传感器信号脚插在esp32的 35脚
温湿度传感器信号脚插在esp32的 35脚
