I just came across this very useful list of sensors:

List of sensors
MQ-2

Sensitive for Methane, Butane, LPG, smoke.
This sensor is sensitive for flamable and combustible gasses.
The heater uses 5V.
The MQ-2 at seeed: Grove - Gas Sensor(MQ2) - Wiki

Search for datasheet: http://duckduckgo.com/?q=%22mq-2%22+...filetype%3Apdf

MQ-3

Sensitive for Alcohol, Ethanol, smoke
The heater uses 5V
The Arduino blog about the "breathalyzer" using a MQ-3 : Arduino Blog » Blog Archive » Arduino Breathalyzer: Calibrating the MQ-3 Alcohol Sensor
The MQ303A (also on this page) is like this sensor, but uses a lower heater voltage.

MQ-4

Sensitive for Methane, CNG Gas
The heater uses 5V.

MQ-5

Sensitive for Natural gas, LPG
The heater uses 5V.

MQ-6

Sensitive for LPG, butane gas
The heater uses 5V.
The MQ-6 at seeed: Electronic brick - Gas sensor(MQ6) - Wiki
The MQ306A (also on this page) is like this sensor, but uses a lower heater voltage.

MQ-7

Sensitive for Carbon Monoxide
The heater uses an alternating voltage of 5V and 1.4V.
A library for the MQ-7 : MQ-7 Breakout Arduino Library
The MQ307A (also on this page) is like this sensor, but uses a lower heater voltage.

Search for datasheet: http://duckduckgo.com/?q=%22mq-7%22+...filetype%3Apdf

MQ-8

Sensitive for Hydrogen Gas
The heater uses 5V.

Search for datasheet: http://duckduckgo.com/?q=%22mq-8%22+...filetype%3Apdf

MQ-9

Sensitive for Carbon Monoxide, flammable gasses.
The heater uses an alternating voltage of 5V and 1.5V. It depends on the gases how to use that alternating voltage. If only Carbon Monoxide is tested, the heater can be set at 1.5V.
The MQ309A (also on this page) is like this sensor, but uses a lower heater voltage.

Search for datasheet: http://duckduckgo.com/?q=%22mq-9%22+...filetype%3Apdf

MQ131

Sensitive for Ozone
The heater uses 6V.

The load-resistor is 100k...200k, which is a lot higher than for other sensors. This sensor is also very sensitive. It measures in ppb (parts per billion) where other sensors measure in ppm (parts per million).

MQ303A

Sensitive for Alcohol, Ethanol, smoke (just like the MQ-3)
The heater uses 0.9V
An example for the MQ302A MQ3 (or MQ303a) Alcohol Sensor Arduino Guide | insapio polymath
It detects the same gasses as the MQ-3, but uses a lower heater voltage.

MG811

Sensitive for Carbon Dioxide (CO2).
The heater uses 6V.
The signal from this gas sensor can be connected to the Arduino, but it's better to amplifly the signal with a OpAmp.
