We've released the Seeed Gas Sensor Selection Guide, it will help you choose the gas sensor that best suits your needs.

The Grove - Gas Sensor(MQ2) module is useful for gas leakage detecting(in home and industry). It can detect LPG, i-butane, methane, alcohol, Hydrogen, smoke and so on. Based on its fast response time. measurements can be taken as soon as possible. Also, the sensitivity can be adjusted by the potentiometer.

For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your using of the product.


Hot-swapping the grove may lead to IC burnout, please turn off the power of the main board before swapping grove.


  • Wide detecting scope

  • Stable and long lifetime

  • Fast response and High sensitivity


More information about the gas sensor, please refer to this manual.
