This project creates a smart mirror that displays information (time, weather, calendar) when someone approaches, and turns off the display when no one is present. The PIR sensor detects motion and triggers the display via Raspberry Pi. The two-way mirror makes the display invisible when off.<\/p>\n
Difficulty:<\/strong> Advanced A PIR sensor mounted on the mirror frame detects when someone approaches. A Raspberry Pi runs MagicMirror software that displays information.
