SONOFF DW2-RF 433MHz - Window Door Alarm Sensor Smart Home suitable for RF Bridge

Article description:

433MHZ RF wireless door/window sensor

Doors and windows as entrances and exits are the weakest points of your house. An unsecured door or window is like an obvious "WELCOME" sign to a burglar, which is why door/window sensors are also known as "entrance sensors".

As one of the most popular home security devices, the DW2-RF Wireless Door/Window Sensor is smart enough to tell you whether your door or window is open.

The sensor comes with a 3M adhesive tape, making it easy to move and remove. It can easily work upside down and sideways as long as the magnet is less than 5mm from the sensor, although it makes no difference how the sensor is attached.

It is battery operated and has low power consumption, so the battery can last up to 2 years.

A 433.92MHz radio gateway is required for this sensor.

The matching Sonoff Bridge is available in the shop as a Tasmota version. This means your data is completely protected as nothing is sent to the cloud.
