MQ Gas Sensor Breakout Board

The MQ Gas Sensor Breakout 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.
