## What is Mood Central?

With this app you can connect your smartphone with your MOOD devices via Bluetooth Low Energy and configure your devices, view historical data, set alarms and thresholds, set activity etc.

MOOD is an easy to use CO2 monitoring device and watchdog that lets you know right away if the ventilation in your room is sufficient.

You can build your own MOOD devices by reading our detailed online tutorial that contains all necessary information. You will find a bill of materials that contains all required parts online.
Technical background knowledge and dealing with soldering iron is necessary. And if you own a 3D printer you can print an appropriate case.
