Have you ever wanted to stream real-time air quality data from a Bluetooth sensor straight into the cloud — without any expensive gateway or IoT server?
In this tutorial, we’ll show you how to use the BleuIO USB dongle and a HibouAir sensor to capture CO2, temperature, and humidity readings over Bluetooth Low Energy (BLE), then automatically log them into Google Sheets for easy tracking and visualization.

By the end, you’ll have a live data logger that updates your Google Sheet every few seconds with real environmental readings — and you’ll even learn how to create charts directly inside Google Sheets.
