For this project, I am using Bluetooth Low Energy USB dongle called BlueIO, which will act as a central device to retrieve data. Hibou Air Quality Monitor which will serve as a peripheral device to transmit the data. The script is simple to use and can be used for other purposes such as showing real-time air quality data; temperate, humidity, pressure, particle matters etc.The data could be later stored on a cloud service of choice.
Things we need:
Google chrome version 78 or later (windows)
BleuIO — Bluetooth Low Energy Adapter
Hibou Air Quality Monitor sensor device
