Product description: The Aqara Vibration Sensor T1 features a high-precision acceleration sensor that detects vibration, tilt, and drops of the object it is attached to. It can trigger alarms or home automations, making it a practical solution for home security. Key Features: - Precise Detection, Instant Alerts: The Vibration Sensor T1 detects activities such as vibration, tilt, or drops—for example, when a drawer is opened or a painting is moved. It sends instant alerts through the hub* and push notifications. - Adjustable Sensitivity and Detection Interval: Offers high, medium, and low sensitivity levels, along with customisable detection intervals from 1 to 10 seconds. Whether protecting a high-value jewelry box or a school locker, the sensor can be precisely adjusted to ensure reliable alerts. - Triple-Tap Automation: Tap three times on the installed surface to trigger preset scenes like turning on lights, ringing the doorbell, or switching to home mode—no app or voice control needed. - Matter over Bridge Support**: Supports Matter over Bridge, enabling seamless integration with major third-party platforms such as Apple Home, Google Home, and Amazon Alexa. - Long-Lasting Battery Life: Powered by two CR2032 batteries and Zigbee 3.0, the sensor offers up to two years of battery life. Disclaimer: *A compatible Aqara Hub is required, and the hub is sold separately. For audible alerts, the hub must feature a built-in speaker. ** To use the device with a particular Matter ecosystem, a Matter Controller of this ecosystem and a Matter-compatible Aqara hub are required.
