ESP8266饮水机的代码可以分为两部分:ESP8266的固件代码和饮水机的控制代码。ESP8266的固件代码可以使用Arduino IDE进行编写,控制代码可以使用C++或者其他语言进行编写。下面是一个简单的ESP8266饮水机代码示例,供您参考:
```C++
#include <ESP8266WiFi.h>
#include <PubSubClient.h>
#include <OneWire.h>
#include <DallasTemperature.h>
const char* ssid = "your_SSID";
const char* password = "your_PASSWORD";
const char* mqtt_server = "your_MQTT_SERVER_IP_ADDRESS";
OneWire oneWire(2); //D4
DallasTemperature sensors(&oneWire);
WiFiClient espClient;
PubSubClient client(espClient);
void setup_wifi() {
delay(10);
Serial.println();
Serial.print("Connecting to ");
Serial.println(ssid);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.println("WiFi connected");
Serial.println("IP address: ");
Serial.println(WiFi.localIP());
}
void reconnect() {
while (!client.connected()) {
Serial.print("Attempting MQTT connection...");
if (client.connect("ESP8266Client")) {
Serial.println("connected");
client.subscribe("drinkWater");
} else {
Serial.print("failed, rc=");
Serial.print(client.state());
Serial.println(" try again in 5 seconds");
delay(5000);
}
}
}
void setup() {
Serial.begin(9600);
setup_wifi();
client.setServer(mqtt_server, 1883);
sensors.begin();
}
void loop() {
if (!client.connected()) {
reconnect();
}
client.loop();
sensors.requestTemperatures();
float tempC = sensors.getTempCByIndex(0);
Serial.print("Temperature: ");
Serial.println(tempC);
if (tempC > 20) {
client.publish("drinkWater", "1");
delay(5000);
}
}
```
这个示例代码使用了ESP8266的WiFi功能和MQTT通讯协议,通过温度传感器监测水温,如果水温超过20摄氏度,就通过MQTT发布一条消息,控制饮水机进行出水操作。注意:这只是一个简单的示例,实际的代码需要根据具体的硬件和需求进行编写。
