Description

Tip

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

How to choose a gas sensor?

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

There are different gas detectors for sale, like  MQ2, MQ3, MQ5, and MQ9. Below is a contrast table of them.

Note

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