Tip
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(MQ5) module is useful for gas leakage detecting(in home and industry). It can detect LPG, natural gas, town gas 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.
Note
Hot-swapping the grove may lead to IC burnout, please turn off the power of the main board before swapping grove.
