Sending BLE Air Quality Data to Arduino Cloud Using BleuIO

This tutorial walks you through a tiny, privacy-first web app that reads only the advertised CO2 level from a nearby HibouAir sensor using a BleuIO USB BLE dongle. Renders it as a color bar with a simple “High CO2” warning when your threshold is crossed.
