Experimental analog-circuit gas detector / alarm

For anyone interested I've put online on my website a description of my experiments resulting in
the development of an experimental gas detector / alarm based on analog circuitry, and not involving any digital electronics :

The detector / alarm system was primarily geared toward natural gas (methane) and butane, but there were
interesting surprises with what it sniffed.

" Hi...i am a new user here. I took a look at your circuit and there a few things that I can mention. Firstly, if you need something as complex as a GSM Modem, you will need to create a LabVIEW instrument for it if that is possible. If you know the exact input you are going to receive, you can use something like a PIECEWISE_LINEAR_VOLTAGE source which is in the Sources Group and the SIGNAL_VOLTAGE_SOURCES Family. "

I think you are in the wrong thread here.
