The script listens for Bluetooth Low Energy (BLE) advertising packets, decodes CO2, temperature, and humidity, and posts fresh readings to your Adafruit IO feeds every few seconds. The result is a clean, shareable dashboard that updates in real time—perfect for demos, labs, offices, classrooms, and proofs of concept.
