Hi everyone,
I’d like to share a small hobby project we recently built using **Node-RED**. The idea was to create an **air quality dashboard** that collects data from a BLE sensor and visualizes it in real time.
For this, we used a **BLE USB dongle (BleuIO)** to handle the Bluetooth Low Energy communication, together with Node-RED for the data flow and dashboard. The project covers scanning for the sensor, retrieving the air quality data, and presenting it on a simple UI.
We documented the steps in detail here: [Using BleuIO with Node-RED to Build a BLE Air Quality Dashboard - BleuIO - Create Bluetooth Low Energy application](https://www.bleuio.com/blog/using-bleuio-with-node-red-to-build-a-ble-air-quality-dashboard/)
Hopefully this is useful for anyone interested in combining BLE devices with Node-RED. I’d be happy to answer any questions or hear suggestions for improvements.
