Example: Building a Simple IoT Weather Station

Let’s look at a basic example of how to create a simple IoT weather station using an ESP32 board and the MQTT protocol:


#include 
#include 
#include 

const char* ssid = "YourWiFiSSID";
const char* password = "YourWiFiPassword";
const char* mqtt_server = "YourMQTTBroker";

#define DHTPIN 4
#define DHTTYPE DHT22

WiFiClient espClient;
PubSubClient client(espClient);
DHT dht(DHTPIN, DHTTYPE);

void setup() {
  Serial.begin(115200);
  setup_wifi();
  client.setServer(mqtt_server, 1883);
  dht.begin();
}

void setup_wifi() {
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.println("WiFi connected");
}

void reconnect() {
  while (!client.connected()) {
    if (client.connect("ESP32Client")) {
      Serial.println("MQTT connected");
    } else {
      delay(5000);
    }
  }
}

void loop() {
  if (!client.connected()) {
    reconnect();
  }
  client.loop();

  float h = dht.readHumidity();
  float t = dht.readTemperature();

  if (!isnan(h) && !isnan(t)) {
    String payload = "Temperature: " + String(t) + "°C, Humidity: " + String(h) + "%";
    client.publish("weather/data", payload.c_str());
  }

  delay(30000);
}

This code connects an ESP32 board to Wi-Fi, reads temperature and humidity data from a DHT22 sensor, and publishes the data to an MQTT broker. This simple example demonstrates the basic principles of IoT development, including device connectivity, sensor integration, and data transmission.
