The Grove - Gas Sensor module is useful for gas leakage detecting(in home and industry). It can detect LPG, i-butane, methane, alcohol, Hydrogen, somke 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. Â There are different gas detectors for sale, like Â MQ2, MQ3, MQ5 and MQ9. Below is a contrast table of them.
