Description
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.
There are different gas detectors for sale, like MQ2, MQ3,MQ5andMQ9. Below is a contrast table of them.
| Sysmbol | MQ-2 | MQ-3 | MQ-5 | MQ-9 |
| Detect Gas | Combustible Gas、Smoke | Alcohol Vapor | LPG, Natural Gas, Town Gas | Carbon Monoxide, Coal Gas, Liquefied Gas |
| Detect Concentration | 300-10000ppm | 0.04-4mg/L Alcohol | 300-10000ppm | 10-1000ppmCO;100-10000PPm Gas |
Features
High sensitivity to Combustible gas in wide range
Stable performance, long life, low cost
Fast response
Wide detection range
Simple drive circuit
For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your using of the product.
Note
Hot-swapping the grove may lead to IC burnout, please turn off the power of main board before swapping grove.
