433MHz RF radio door/window sensor
Doors and windows as entrances and outputs are the weakest points in your house. An unsecured door or an unsecured window is like an obvious "welcome" sign, for a burglar, so door/window sensors are also known as a "input sensor".
As one of the most popular home safety devices, the wireless door/window sensor DW2-RF is intelligent enough to tell you whether your door or window is open.
The sensor is delivered with a 3m adhesive tape, so it is easy to move and remove. It can easily work and work on the side as long as the magnet is less than 5 mm from the sensor, although it makes no difference as the sensor is attached.
It is battery operated and has low power consumption so that the battery can last up to 2 years.
A 433.92MHz radio gateway is required for this sensor.
The right Sonoff Bridge is available in the shop as a Tasmota version. This means that your data is completely protected because nothing is sent to the cloud.
