Mostly made by Aosong. Here is the datasheet. The library from Adafruit on GIT works  fine.  The library has been attached here also in case the GIT one is not available for any reason.

There are example codes in the library. Wiring the module is pretty simple.

The module works on 3.3v – 5v and uses I2C for communication.

As per the datasheets the module will malfunction under harsh conditions and contamination. But it may recover if left for sometime.
