Cytron Technical Forum

Hi guys, i've recently purchase a MQ-3 series alcohol gas sensor from cytron through online, and the sensor comes with a mini board attached with a small board below it and a connecting wire which seems to be used to connect to an Arduino board. As im currently doing my final year project with it, do any of u guys know what is the mini board called? So that i could look further to see the informations regarding it.

Isn't all the info is stated on the datasheet of that sensor. I belieave the small board that you mentioned is just the breakout board of the sensor so that user can connect it easily. Just connect the 3 wires to Arduino accordingly. Then it comes to software part...
