How to choose a gas sensor ? The Grove - Gas Sensor module is useful for gas leakage detecting(in home and industry)
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 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.
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|
Hot-swapping the grove may lead to IC burnout, please turn off the power of the main board before swapping grove.
High sensitivity to Combustible gas in wide range
Stable performance, long life, low cost
Wide detection range
Simple drive circuit
|Dimensions||40mm x20mm x18mm|
