Tuya WiFi Door Sensor with Siren

The Tuya WiFi Door Sensor with Siren is a wireless smart security sensor designed to monitor the opening and closing of doors, windows, cabinets, drawers, and other access points. Unlike a conventional magnetic contact sensor, this version combines contact detection with a built-in audible siren, providing both local alarm output and smartphone notifications when an unauthorized opening is detected.

The sensor connects directly to a 2.4GHz WiFi network, allowing it to communicate with the Tuya Smart and Smart Life applications without requiring a separate gateway or Zigbee hub. Once configured, users can monitor the sensor status remotely and receive notifications when the monitored door or window changes between open and closed states.

A built-in 120dB acoustic alarm provides an immediate local warning when the sensor is triggered. This makes the device useful not only for status monitoring but also as a compact security alarm for entrances, windows, cabinets, shops, offices, and other areas where unauthorized access needs to be detected. The alarm function can work alongside mobile notifications to provide both local and remote awareness.

The sensor is powered by two AAA 1.5V batteries, eliminating the need for wiring at the installation point. Its wireless design allows it to be mounted on doors and windows using the appropriate adhesive or mounting method. The magnetic contact mechanism detects separation between the main sensor and its corresponding magnet, making it suitable for monitoring physical access points.

Through the Tuya ecosystem, the sensor can also participate in smart-home automation. An opening event can be used as a trigger for compatible Tuya devices, such as smart lights, cameras, or other security equipment. Supported versions can also work with Amazon Alexa and Google Assistant, providing additional integration with a smart-home environment.

The Tuya WiFi Door Sensor with Siren is therefore suitable for applications requiring more than a simple door-status notification. Its combination of WiFi connectivity, magnetic detection, built-in high-volume alarm, mobile alerts, and smart automation makes it a practical security component for residential and commercial installations.
