Pololu item #: 1479
Price: $0.95
Quantity:

This carrier board is designed to work with any of the MQ-series gas sensors, simplifying the interface from 6 to 3 pins—ground, power and analog voltage output—that are broken out with a 0.1" spacing, making the board compatible with 0.1" headers and standard breadboards and perfboards. This board has two mounting holes and provides convenient pads for mounting the gas sensor’s required sensitivity-setting resistor.

Pololu item #: 1639
Price: $0.95
Quantity:

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.
