From my perspective bedroom is the most climate sensitive room, because healthy sleep is quite dependent on the bedroom environment. We spend around one third of our lives in bed so to make it more comfortable and to encourage deep and restful sleep I decided to build some monitoring and controlling device, which helps me to get right environment in bedroom without my continuous invasion.
I find it quite difficult to get nice enclosure, so I decided to use Schneider Electric blind cover plate to mount necessary sensors, and embed device into the wall. Prototype device consists of CO2, temperature and humidity sensors, can set up desired temperature in the room via 2 buttons, has buzzer, and can be controlled over Wifi network connection, using COAP protocol.
