About this app

With this app you can monitor the indoor air quality measurements performed by an ARANET4 device. You can receive alerts when CO2 exceeds a certain level, e.g. 1000 ppm.

co2Hook connects to the ARANET4 device vial Bluetooth LE, gets it's current measurements and shows them as an Android notification. For CO2 measurements, you can configure a threshold. If the measurement is above that threshold, co2Hook will notify with sound and vibration. Android Wear notifications are supported as well. You can get an ARANET4 device here: https://aranet4.com/. Feel free to raise a pull request if you want co2Hook to support other CO2 measurement devices.
