Aqara Door and Window Sensor T1
Smart contact sensor for doors, windows & more
The Aqara Door and Window Sensor T1 is a compact, battery-powered contact sensor designed to detect open or closed states of doors, windows, drawers, or cabinets. Paired with a Zigbee 3.0 hub, it enables instant notifications, home automation triggers, and smart‑security alerts whenever an entry point is opened or closed.
Smart Door & Window Monitoring for Home Security & Automation
The Aqara Door and Window Sensor T1 monitors the open/closed status of doors, windows, drawers, or cabinets by detecting the proximity between its sensor unit and a magnet. This tiny, unobtrusive device uses minimal power and sends real‑time updates to your smart home hub — ideal for home security, occupancy sensing, and automation routines such as lighting, climate control, or alerts when a door is opened unexpectedly.
How It Works
When the door, window, or surface closes, the magnet aligns with the sensor unit — the sensor reads this as “closed.” When the magnet moves away (i.e. door/window opens), the sensor registers “open” and sends a signal via Zigbee 3.0. You can then trigger actions like notifications, alarms, lights, or other smart devices. The sensor is easy to install — just stick it with the included adhesive, no tools needed.
