> This should do the job. The mounting holes and module size in pcb may be incorrect as it is from a random MQ type module which may not be the same as yours. If you want mounting holes in pcb you need to drag a hole over the circle in silkscreen (by default the mounting holes are only on silkscreen, they are not drilled.) The gas sensor in breadboard isn’t quite right, but I;m not a good enough graphic artist to correct it.

Check if the connectors are the same

Bye for now. It’s 12 midnight here. @vanepp can you help me reply him if he asks anything?

Hello, it seems to be a similar connector. May I ask a small question? Can the name be changed to MQ - 2?

Open the SVG with a text editor and change this section

```auto

      x="355.77576"
      id="label"
      font-family="'Droid Sans'"
      text-anchor="middle"
      fill="#000000">MQ-5</text>

```

to

Save the file.

Then right-click the part → edit

Do you have the libraries for MQ-6 MQ-2 and MQ-135.  
I am using these sensors for a project, I have found the MQ- 4 and MQ-7 libraries but I can’t find these sensors libraries(MQ-2, Mq-6 and Mq-135). If anyone is looking for the libraries for MQ-4 and MQ-7, just reply to this message and I will send it to you.  
Thank you
