Xiaomi PM2.5, tVOC, CO2 sensor

Hi, In aliexpress I found these two relative cheap Co2, tVOC and PM2.5 sensor from wifi xiaomi.

I was wondering if anybody had experience with these sensors? I think they could be added to the xiaomi (wifi) binding.

Here are some links:

and on offer from geekbuying:

I have just purchased the Clear Grass, this device is very good. I think that its measurements can trigger many devices.

Is there anyone that tried to add it at the xiaomi binding?
