描述
Grove – Gas Sensor(MQ9) 氣體傳感器 一氧化碳，煤氣，液化氣
Grove – Gas Sensor(MQ9) 氣體傳感器模組可用於檢測氣體洩漏（在家庭和工業中）。它可以檢測液化石油氣，異丁烷，甲烷，酒精，氫氣，somke等。根據其快速響應時間，可以盡快進行測量。靈敏度也可以通過電位器進行調整。每個格魯夫 – 氣體傳感器套件包含一個氣體傳感器基座和四個檢測器， 包括 MQ2，MQ3， MQ5 和 MQ9。下面是他們的對比表。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，煤氣 | 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 |
注意事項：MQ 系列感測器所偵測到的值只反映在允許的誤差範圍內近似的氣體濃度趨勢，但並不代表確切的氣體濃度。空氣中某些組分的檢測通常需要更精確和更昂貴的儀器，這不能用單個氣體傳感器來完成。如果您的項目旨在獲得非常精確的氣體濃度，那麼我們不推薦這種氣體傳感器。
特徵
- 對可燃氣體有很高的敏感度
- 性能穩定，壽命長，成本低
- 反應快
- 檢測範圍寬
- 簡單的驅動電路
注意
熱插拔槽可能會導致IC燒毀，請在交換槽之前關閉主板的電源。

Datasheet
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
NoteHot-swapping the grove may lead to IC burnout, please turn off the power of main board before swapping grove.
