Sonoff DW2 Wifi Door Window Alarm Sensor

 

Sonoff DW2 Wifi Door Window Alarm Sensor is a great security measure for your home. You can attach one part of this product, which consists of two parts, to your door or window. You need to glue the other part to the frame. The two parts in contact with each other separate when the door is opened, and if this happens, it sends you a notification.

 

You can control all your Sonoff brand products with the eWeLink application you will install on your phone.
