Ambient Adaptive Noise Bar with BleuIO and HibouAir
Hi there,
If you’re interested in Bluetooth Low Energy projects, here’s a practical example you may like: a simple ambient noise monitor built around BLE advertisements.
What this tutorial shows
✓BLE advertisements
– read HibouAir broadcast data without pairing ✓Privacy-first monitoring
– no audio recording, only decoded noise values ✓Visual noise awareness
– use a 40–80 dBSPL color bar and threshold banner
The page shows a 40–80 dBSPL color bar and a subtle “shhh” banner when your threshold is crossed. It is a simple way to visualize sound level changes without capturing or storing audio.
It’s ideal for libraries, classrooms, and shared offices where awareness matters but recording doesn’t.
