Choosing the right GSM module/shield + Temp sensor

Other Hardware General Electronics

Hello

I want for my Arduino Mega to be able to connect to the Internet via GSM. Since this is my first Arduino project, I'm looking for a very simple setup both installation and programming. I've seen two models, but not sure which one to choose or if there are others. It will be used in combination with a temp sensor eg. DS18B20. Basically, what I want to do is to monitor the temp in my cabin.

GSM Shield with integrated antenna:

GSM Shield antenna not integrated and not included:

What are the major/important differences between them except for the up/download speed of 85.6kbps and 460kbps. I would rather use the integrated version since it does not require extra space for antenna, however, I find anything on the operating temp for Bluevia!

Also, what is the difference between the DS12B20 and TMP36 temp sensor? Can I use any kind of temp sensor as I want, or do they have to be specifically made for Arduino?

Oh, btw, I live in north Europe.

Thanks

A Mega for just a sensor seems to me oversized and too big, a Uno should be enough.

The official shield is certainly the easiest choice for programming: the library is included in the IDE and there are a lot of examples. The antenna included is a problem already solved for you, no worries about it. Speed is enough for a temperature reading: a couple of bytes!

Are you from Norway?

It just happens that I have got one Mega for free from some one ^^
What if I increase the # of sensors to 3 or 4? Still enough with 85 kbps?
Yeah, I'm from Norway. How did you know that? =)

Ahaha just guessing! I'm from Italy!

The point is that I think younare going to make an HTML server with a couple of lines that displays the reading of you sensors.
To transfer such information (something like a hundred of char) at that speed is simply immediate!
