The Aqara Vibration Sensor (DJT11LM) is a compact security device designed to detect movement and vibrations on the surfaces where it is placed. Using the Zigbee wireless protocol, this small white sensor can be integrated into your smart home system via the Aqara Home app for Android 5.0+ or the Apple Home app for iOS 10.3+, allowing you to receive notifications whenever an object is moved or tampered with. Measuring just 36 x 36 x 9 mm, its discreet size makes it easy to hide on drawers, doors, or valuable items using the included adhesive sticker. It runs on a CR2032 battery and features a built-in LED indicator to show its status, operating reliably in temperatures ranging from -10°C to +45°C and humidity levels up to 95%. This makes it a practical choice for those wanting to monitor the security of specific household objects without installing bulky equipment.
