SONOFF Wi-Fi Door/Window Sensor

The Sonoff DW2 sensor can help secure your door or window to let you know whether your home is safe wherever you are. The sensor can trigger an alarm on your smartphone to inform you of an intruder when the door or window is opened. In addition, connect the SONOFF wireless IP camera and you can view who the intruder is on the sensor page of the eWeLink app. You can also check the real-time opening and closing status on the app.

Real-time battery-level display and low-battery reminders ensure that you know exactly how long the sensor can run and when you need to replace batteries. With simple peel-and-stick installation, it is easy to fit onto door frames and window sills.

DW2-Wi-Fi comes in two pieces, the transmitter which fits onto the door or window and the magnetic switch that attaches to the frame.

The sensor can work for up to 3 months if the door/window is opened or closed three times a day.
