Looking for MQ-2 Gas Sensor

[RAPTOR7762]

MQ-4 Sensor Part

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. MQ-5.fzpz (31.9 KB) Peter
