IoT

Key Components

• Sensors & Actuators: Collect data and perform actions
• Connectivity: WiFi, Bluetooth, cellular, or other protocols
• Data Processing: Edge computing or cloud-based analytics
• User Interface: Mobile apps or web dashboards
• Security: Encryption and authentication mechanisms

IoT Applications

// Example: Arduino IoT Temperature Sensor
#include <WiFi.h>
#include <HTTPClient.h>
#include <DHT.h>

#define DHT_PIN 2
#define DHT_TYPE DHT22

DHT dht(DHT_PIN, DHT_TYPE);
const char* ssid = "your_wifi_ssid";
const char* password = "your_wifi_password";
const char* serverURL = "https://api.iot-platform.com/data";

void setup() {
  Serial.begin(115200);
  dht.begin();
  
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to WiFi...");
  }
}

void loop() {
  float temperature = dht.readTemperature();
  float humidity = dht.readHumidity();
  
  if (!isnan(temperature) && !isnan(humidity)) {
    sendSensorData(temperature, humidity);
  }
  
  delay(60000); // Send data every minute
}

void sendSensorData(float temp, float hum) {
  HTTPClient http;
  http.begin(serverURL);
  http.addHeader("Content-Type", "application/json");
  
  String payload = "{\"temperature\":" + String(temp) + 
                   ",\"humidity\":" + String(hum) + "}";
  
  int httpResponseCode = http.POST(payload);
  http.end();
}
