ESP32自动浇花系统通常会利用物联网技术,结合Arduino或Espressif平台编写代码,通过WiFi连接远程控制设备,定时开关水阀来进行浇水。以下是一个简化的米思琪(MiSoul)风格的ESP32自动浇花系统代码示例:
```cpp
#include <ESP8266WiFi.h>
#include <WiFiClientSecure.h>
#include <DNSServer.h>
// WiFi设置
const char* ssid = "your_SSID";
const char* password = "your_PASSWORD";
// 云端服务器信息
const char* mqtt_server = "mqtt.your_server.com";
const int mqtt_port = 1883;
const char* mqtt_topic = "home/garden/sprinkler";
// 定义定时任务间隔
const unsigned long watering_interval = 60 * 60 * 2; // 每两小时浇水一次
DNSServer dnsServer;
WiFiClientSecure client;
void setup() {
Serial.begin(115200);
if (!WiFi.begin(ssid, password)) {
Serial.println("Connection failed!");
return;
}
while (WiFi.status() != WL_CONNECTED) {
delay(1000);
Serial.print(".");
}
Serial.println();
if (!client.connect("ESPClient", mqtt_server, mqtt_port)) {
Serial.println("MQTT connection failed!");
return;
}
// 注册DNS解析服务
dnsServer.setDomain("your_domain");
}
void loop() {
// 连接并发布主题到MQTT服务器
if (dnsServer.processNextQuery(client)) {
String host = dnsServer.getHostByName(dnsServer queries[0].name);
WiFiUDP udp;
udp.begin(host.c_str(), 1883);
String message = "sprinkle_start";
WiFiClientSecure secureClient(udp);
if (secureClient.connected()) {
secureClient.publish(mqtt_topic, message);
} else {
Serial.println("Publishing failed.");
}
} else {
delay(1000); // 如果DNS查询失败,等待一秒钟再试
}
// 按照预定时间间隔浇水
static unsigned long lastWatered = 0;
if (millis() - lastWatered > watering_interval) {
lastWatered = millis();
publishSprinklerStatus("watering"); // 根据实际硬件操作编写这个函数
}
delay(1000); // 程序主循环休眠时间
}
void publishSprinklerStatus(String status) {
// 发布喷水状态到MQTT主题
// 这里可以添加具体的代码来发送状态更新,例如:
// secureClient.publish(mqtt_topic + "/status", status.c_str());
}
```
