Build your dream smart home starting with this Mi smart home motion and light sensor. Using passive infrared technology, it effectively senses movement and changes in lighting in a particular room or space. Configure with the app to connect with other smart devices at home: Automatically turn the bathroom light on when someone uses it, play music when a person enters a room, or automate your curtains so they close when the sun shines too bright. It comes with a hemispherical magnetic base so you can rotate it any angle you want. Attach on a magnetic surface or stick on a wall to secure in place. Simple, minimalist look that will blend well with any interior style.
