Thanks a lot Ahmad for your answer.
But I think is better if we can make work this sensor with OMG for some reasons.
To make it work via WiFi, the RFLink need to much boards for my opinion.
The Bruh sensor is great but it use WiFi power and so is not great to use it with battery
The last reason but same important is that with this sensor work on OMG
I think is good think for OMG community grow 
Thanks again
