MQ-2
Sensitive for Methane, Butane, LPG, smoke.
This sensor is sensitive for flamable and combustible gasses.
The heater uses 5V.
MQ-3
Sensitive for Alcohol, Ethanol, smoke
The heater uses 5V
The Arduino blog about the "breathalyzer" using a MQ-3 :
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.
MQ-7
Sensitive for Carbon Monoxide
The heater uses an alternating voltage of 5V and 1.4V.
MQ-8
Sensitive for Hydrogen Gas
The heater uses 5V.
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.
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).
MQ137
Sensitive for Ammonia.
The heater uses 5V.
