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.
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.
Combustible Gas, Smoke
|Alcohol Vapor||LPG, Natural Gas, Town Gas||Carbon Monoxide, Coal Gas, Liquefied Gas|
|Concentration||300-10000ppm||0.04-4mg/L Alcohol||300-10000ppm||10-1000ppmCO;100-10000PPm Gas|
High sensitivity to Combustible gas in wide range
Stable performance, long life, low cost
Wide detection range
Simple drive circuit
Hot-swapping the grove may lead to IC burnout, please turn off the power of main board before swapping grove.
