Simple breakout board for the SparkFun MQ-3, MQ-4, MQ-6 and MQ-7 gas sensors.
The SparkFun BOB-0889 is designed to interface with the MQ-3, MQ-4, MQ-6 and MQ-7 gas sensors which all use the same footprint. Just add VCC at 5V, GND, and a resistor to an ADC!
Note: This is only a PCB interface board. You still require the necessary sensor to attach to it.
Dimensions: 16.8mm diameter
