This kit includes all the components required to connect a MQ gas sensor( MQ2-2, MQ-3, MQ-4, MQ-6 and MQ-7.) to the Arduino board.
This kit includes a specially designed PCB for any of the sensors mentioned before, one 10Kohm resistor, one 10Kohm potentiometer used to adjust the sensor sensibility and a 3 pin header.
When it comes to interfacing this brick with the other components, we recommend using these jumper wires.
This kit requires soldering, just like in the video below.
