Tuya WiFi Door Sensor

The Tuya WiFi Door Sensor is a compact wireless magnetic contact sensor designed to monitor the opening and closing status of doors, windows, cabinets, drawers, and other access points. It consists of a main sensor unit and a magnetic contact piece that detects separation between the two components. When the monitored door or window is opened, the sensor can send a status update or notification through the Tuya Smart or Smart Life application.

The sensor connects directly to a 2.4GHz WiFi network, allowing remote monitoring without requiring a separate Zigbee hub or gateway. Users can check the current open/closed status from their smartphone and configure notifications for door or window activity. The device can also be incorporated into Tuya smart-home scenes, allowing an opening event to trigger another compatible smart device or automation routine.

Powered by two AAA batteries, the sensor is designed for wireless installation without requiring power cables. Its compact two-piece construction can be mounted using adhesive tape or screws, depending on the installation surface and sensor version. Correct alignment between the main sensor and magnetic piece is important for reliable detection; typical versions specify a maximum separation of around 10 mm when the monitored opening is closed.

Through the Tuya platform, the sensor can be used as part of a broader smart-home security and automation system. For example, opening a door can trigger a smartphone notification, activate a smart light, or initiate another configured scene. Compatible versions also support integration with Amazon Alexa and Google Assistant.

The Tuya WiFi Door Sensor is suitable for homes, offices, shops, cabinets, garages, and other indoor areas where monitoring access or creating event-based automation is required. Since this type of sensor is battery powered and wireless, it provides a practical way to add contact monitoring to existing spaces without installing dedicated wired security sensors.
