Getting Started
Follow these steps to set up your first Azure IoT solution.
- Create an IoT Hub in the Azure portal.
- Register a device identity and retrieve its connection string.
- Install the Azure IoT SDK for your preferred language (C#, Python, Node.js, etc.).
- Send telemetry from your device:
// Node.js example
const iotHub = require('azure-iot-device');
const client = iotHub.Client.fromConnectionString(process.env.IOT_HUB_CONNECTION_STRING);
setInterval(() => {
const temperature = 20 + Math.random()*5;
const payload = JSON.stringify({temperature});
client.sendEvent(new iotHub.Message(payload));
}, 5000);
Security Best Practices
- Use X.509 certificates for device authentication.
- Enable per‑device SAS tokens with limited lifetime.
- Apply Azure Policy to enforce secure IoT Hub configurations.
- Utilize Azure Defender for IoT for threat detection.
