IoT big data cloud let's start small!
summary
A hands‑on path from sensor to cloud: an Arduino board + air‑quality and temp sensors (ESP32 on battery) sends JSON payloads over MQTT to ESP32 sending JSON via MQTT every 10s, appears in Arduino Cloud dashboard and in Microsoft Azure IoT Central, and you can trigger a toggle LED command back to the device (works but can be slow). Uses Arduino Cloud free plan and Azure templates; limits include Arduino Cloud free plan: 2 things, 1 day retention. Data export to Azure Blob works; Azure Data Explorer attempt fails.
