CYBERNOVA Wireless 2.4GHZ WiFi Door and Window Sensor，Work with IFTTT ，Smartphone Remote Control

In this video, I'm going to review briefly this SONOFF DW2-Wi-Fi Door/Window sensor and I'm going to show you how you can use with your projects. First of all, this device I purchased from itead.cc, cost less than seven dollars and remember that there is a ZigBee version of this device which is a bit more expensive, about 8.5 dollars. In addition to the ZigBee version, there is also RF 433 version which is the cheapest one ... something like five dollars. A good thing above the Wi-Fi model is that it doesn't require any GateWay or Bridge to operate, so you can connect (it) directly to your access point or router. The package you buy contains the main product which is made of two parts; the moving part and the one that contains a battery and logic, manuals and this double sided tape you can easily glue (attach) on your door or window. This device, same as most of the SONOFF Wi-Fi device
