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,MQ3MQ5 and MQ9. Below is a contrast table of them. You can switch the detector on the base according to specific target gases.
