interesting. looking over the specs on this sensor online, it looks like it detects not only different gases but also smoke.
it interfaces via a analog signal.
So, that looks like it would hook to something like an Arduino?
I have a spare Arduino laying around that I use to play with something like this.
Since it would be costly (analog pin-wise) to use the existing analog pins on my Raspberry Pi (main controller), and this doesn't seem to support digital I2C networking and the Arduino does...
I could possibly use the Arduino as a sacrifical lamb for it's analog pins, hook its I2C connection into with my Raspberry Pi and then have them both talking together while not using any additional analog pins on my main controller.

If it works, that has the potential to allow someone to setup a small network of arduino's with sensors placed wherever they want as long as they can get a digital I2C connection back to a main control board.
I've never tried this before, but I've read about similar things being done.
Programming is not my strength, so it would take me some time to try to figure this one out. But it would be a good challenge!
