SONOFF DW2
WIFI magnetic contact for doors and windows
SONOFF DW2 Wi-Fi wireless door / window sensor comes in two pieces, the transmitter fits on the door or window, and the magnetic switch attaches to the frame.
It can help you secure your door or window to let you know if your home is safe wherever you are.
The sensor will trigger an alarm on your smartphone to remind you of an intruder when the door or window is opened. Connect SONOFF wireless IP camera and you can see who the intruder is in the APP sensors page. Whatever your door or window is open or closed, you can check the opening and closing status in real time on the eWeLink APP.
The real-time battery level display and low battery reminder ensure that you clearly know how long the sensor can work and when to replace the batteries.
