V5 analog sensor hookup guide?

Hey folks,

I’m using an MQ-2 gas sensor for a project on this little breakout (https://www.pololu.com/product/1479), and I’m just wondering the best way to hook it up to the particle. I’ve browsed over some of the other threads regarding this, but I’m wondering if someone has a best go-to setup, can share some experience of what worked (or didn’t) for you, or if particle has an official “this is how you work w/ 5v analog sensors that are current hogs” tutorial or guide somewhere.


Connect VCC to 5 V is supported by the VIN-Pin.
