Mi Door and Window Sensor 2 combines opening/closing detection with a built-in ambient light sensor, giving you a genuine 2-in-1 solution for smart home automation.
Its magnetic induction sensor determines open or closed status instantly, sending real-time alerts to your phone whenever a door or window opens unexpectedly or has been left open too long. The new light sensor detects when ambient lighting is dim and can trigger a smart light for a night-time entry scene, and the compact, lightweight body adheres strongly to virtually anything that opens or closes — doors, windows, drawers, and cabinets alike.
