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.
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.
| 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 |
| 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
Note
Hot-swapping the grove may lead to IC burnout, please turn off the power of main board before swapping grove.

描述
林氣感應器模組用於氣體洩漏檢測 (家用和工業)。可檢測液化石油氣、丁烷、甲烷、乙醇、氫氣、抽煙等。可根據其快速回應時間, 儘快採取測量。並且靈敏度可以由電位器調整。
每個格羅夫-氣體感應器套件由一個氣體感應器基座和四探測器組成, 包括MQ2,MQ3, MQ5和 MQ9。下面是它們的對比表。您可以根據特定的目標氣體在基座上切換探測器.
| Sysmbol | MQ-2 | MQ-3 | MQ-5 | MQ-9 |
| 檢測氣體 | 可燃氣體, 煙霧 | 酒精蒸氣 | 液化石油氣、天然氣、城鎮燃氣 | 一氧化碳、煤氣、液化氣 |
| 濃度 | 300-10000ppm | 0.04-4mg/L 酒精 | 300-10000ppm | 10-1000ppmCO; 100-10000PPm 氣體 |
功能
