Door and Window Sensor Wireless Smart 433MHz RF - Sonoff DW2-RF

Doors and windows that can be used as entrances and exits are the weakest points in the security of your home. An unprotected door or window is like an obvious "Welcome" sign for a thief, so the Sensors of Door/Window are also known as the "Entry Sensor" . As one of the most popular home security devices, the Sensor of Door and DW2-RF Wireless Window is smart enough to know if your door or window is open and you can not only send alert notifications, but also notify you when the entry point is opened, ensuring the security of your home.

Most importantly, the sensor allows you to add a security camera to see who enters your home, providing more details and notes about the unwanted guest. You can send an alert of the opening status of the door / window to the application, which gives you peace of mind when you are not at home.

Verification of historical records can be traced back to the last 3 months and this can help you to look back and check the condition of your home at that time. The lights are turned on in action. You can set the connection in the smart scene of the eWeLink app to connect the sensor and its light to turn on / off the hall light for example when opening the door.

A SonOff Bridge is required to make that connection is possible. Combined with the IFTTT service, the sensor can be used to trigger more devices or routines. This "Device Sharing" feature lets more people in your family know that your home is safe. After sharing the sensor, all shared users will receive the alert about the condition when someone opens the door.

The sensor has 3M adhesive installed, easy to move and remove. It can work perfectly upside down and sideways, as long as the magnet is less than 5mm from the sensor, which makes no difference how the sensor is located. It is battery operated and has low power consumption, which ensures that the battery life can last up to 2 years.
