描述
Grove Multichannel Gas Sensor 多通道有害氣體感測器
Grove – 多通道氣體傳感器是一種內置的MiCS-6814的環境檢測傳感器，可以檢測許多不健康的氣體，並且由於多通道可以同時測量三種氣體，因此可以幫助您監測多於一個加油站。
這個傳感器屬於Grove系統，你可以直接插入 Base Shield，直接和Arduino一起使用，不需要任何跳線。它的接口是I2C，所以插到底座的I2C端口上，然後就可以開始工作了。
注意事項：傳感器值只反映了氣體濃度在允許的誤差範圍內的近似趨勢，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，那麼我們不建議使用這種氣體傳感器。

文件
Grove – Multichannel Gas sensor is a environment detecting sensor with a built in MiCS-6814 which can detect many unhealthful gases, and three gases can be measured simultaneously due to its three channels, so it can help you to monitor the concentration which more than one gas.This sensor is belong to Grove system, and you can plug it onto the Base shield and work with Arduino directly without any jumper wires. The interface of it is I2C, so plug it onto the I2C port of Base shield, then you can start to work it.
Features
- Three fully independent sensing elements on one package
- Built with ATmega168PA
- I2C interface with programmable address
- Heating power can be shut down for low power
- Detectable gases:Carbon monoxide (CO) , Nitrogen dioxide (NO2) , Hydrogen (H2) , Ammonia (NH3) , Methane (CH4) , etc.
