Sparkfun MQ Gas Sensor Carrier
This carrier board is designed to work with any of the MQ-series gas sensors, simplifying the interface from 6 to 4 pins that are broken out with a 0.1" spacing, making the board compatible with 0.1" headers and standard breadboards and perfboards. The board has the same diameter (16.8 mm) as the smaller of the gas-sensor packages, allowing for a low-profile connection.

This breakout board is designed to work with any of the MQ-series gas sensor, simplifying the interface from 6 to 4 pins that are broken out with a 0.1" spacing, making the board compatible with 0.1" headers and standard breadboards and perfboards. The board has a diameter of 16.8 mm, which matches the diameter of the small (plastic) gas sensor packages, providing a more convenient, compact connection within the bounds of the sensor itself.
The two rows of 1 x 2 pins are spaced 0.5" apart allowing the break out board to work with standard breadboards.
Note that we also offer an alternate gas sensor breakout board that has mounting holes, pads designated for the required sensitivity resistor RL, and a convenient three-pin interface.
Connect H1 and A1 to 5 V, GND to ground, and B1 to an ADC input of your microcontroller. A required (but not included) sensitivity-setting resistor, RL, should be connected between B1 and GND. The resistance of RL should be calculated using the datasheet for your particular gas sensor.
The MQ gas sensors have light to no polarity, so the gas sensor will work with the board any way it fits into the 6 pins.

Note: This product consists of the PCB by itself; it does not include a gas sensor, sensitivity resistor, header pins, or any additional hardware.

The MQ-2 sensor allows the measurement of gas concentrations such as propane, butane, methane, LPG as well as alcohol and smoke. Sensor measuring range: up to 10,000 ppm
The MQ-3 sensor allows you to measure the concentration of alcohol vapors. The measuring range of the sensor is in the range of 0.05 mg / L to 10mg / L, and an analogue signal is obtained at the output.
The MQ-4 sensor allows methane concentration measurement. The measuring range of the sensor reaches up to 10,000 ppm and an analogue signal is obtained at the output.
The MQ-6 sensor allows the measurement of LPG, propane and isobutane. The measuring range of the sensor is in the range of 300 - 10.000 ppm, while the output receives an analog signal.
The MQ-7 sensor allows you to measure the concentration of carbon monoxide (carbon monoxide). The measuring range of the sensor is in the range of 10 - 10,000 ppm
The MQ-9 sensor allows the measurement of gas concentrations such as carbon monoxide, propane and methane. Sensor measuring range: 10 - 10,000 ppm
The MQ-8 sensor allows the measurement of hydrogen concentration in the air. The measuring range of the sensor is in the range of 100 - 10,000 ppm.
The MQ-5 sensor allows the measurement of alcohol and gas concentrations, such as methane, LPG, and carbon monoxide. Sensor measuring range: up to 10,000 ppm
