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#define BLINKER_WIFI
#include <ArduinoJson.h>//此库需要放在Blinker.h库前不然会出现编译错误
#include <Blinker.h>
#include <DHT.h>
#define JDQ 12 //继电器信号引脚
#define TR 35 //土壤传感器信号引脚
#define DHTPIN 25 //温湿度传感器信号引脚
#define DHTTYPE DHT11 //温湿度传感器类型
#define ran "SliderKey"

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
