Hands-on Azure Digital Twins Read Online May 2026

We’ll simulate a temperature spike and compute a "high temperature" alert using a . Architecture Pattern: IoT Device → IoT Hub → Azure Function → ADT (patch property) The Function Logic (Python example): import json import logging import azure.functions as func from azure.digitaltwins.core import DigitalTwinsClient from azure.identity import DefaultAzureCredential def main(event: func.EventHubEvent): # Parse telemetry from IoT device telemetry = json.loads(event.get_body().decode('utf-8')) sensor_id = telemetry['sensorId'] new_temp = telemetry['temperature']
