Grove Gas Sensor (MQ9)

PRODUCT DETAILS

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.

Each Grove - Gas Sensor Kit consists of one gas sensor base and four detectors, including MQ2, MQ3, MQ5, and MQ9. Below is a contrast table of them. You can switch the detector on the base according to specific target gases.

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