Can Pi be used in the cold weather

What is the lowest the tempurature you can use a Pi.

May want to set up a Pi to control some lights and garage door opener, but our garage can go down to -20 in some winters.

Would the Pi using a WiFi dongle along with some relays work in that kind of cold

Likewise what is the hottest it can run.

So I guess whats the operating temp?

For electronics moisture is normally more of a problem than cold.

Would it be useful to surround the Pi electronics with a desiccant such as silica gel, in order to absorb moisture in a cold and damp environment?

I have 2 Raspberry Pi's (first generation) sitting outdoors as motion sensing surveillance camera's. The past winter, they frequenct below 0 degree Celsius temperatures. In fact, I took this screen shot of the temperature as displayed by the shell a few weeks ago when the temperature dipped to about -10 degrees Celsius outside.

The only problem I ran into was when it got too cold, the Raspberry Pi would just stop working. I found out that the SD card wasn't making connection with the Raspberry Pi. I guess the cold caused the metal connector to shrink back? I dunno. I wedged some paper in there and that solved the problem. I don't know if this is an issue with the B+ or Raspberry Pi 2.

That article pretty much summed it up for me. I was worried about cold weather too. My Pi hit 14F last night.
