IoT and Smart Devices: How Connected Technology is Transforming Industries

The Internet of Things (IoT) connects billions of devices worldwide, creating unprecedented opportunities for automation, monitoring, and data-driven decision making.

IoT Data Pipeline Example

// Node.js — IoT sensor data processing pipeline
import mqtt from 'mqtt';

const client = mqtt.connect('mqtt://iot-broker.example.com');

interface SensorReading {
  deviceId: string;
  temperature: number;
  humidity: number;
  timestamp: string;
}

client.subscribe('factory/sensors/+/data');

client.on('message', async (topic, message) => {
  const reading: SensorReading = JSON.parse(message.toString());
  
  // Anomaly detection
  if (reading.temperature > 85) {
    await sendAlert({
      level: 'critical',
      message: `Device ${reading.deviceId}: Temperature ${reading.temperature}°C exceeds threshold`,
      action: 'Initiate cooling sequence',
    });
  }
  
  // Store in time-series database
  await db.sensorReadings.insert(reading);
  
  // Update real-time dashboard
  ws.broadcast(JSON.stringify({
    type: 'sensor_update',
    data: reading,
  }));
});
