商品說明

Grove – Multichannel Gas Sensor v2 多通道有害氣體感測器

Grove-多通道氣體傳感器V2具有4個測量單元,每個測量單元都對各種氣體敏感,這意味著您可以同時獲取四組數據。通過這四組數據還可以判斷出不同種類的氣體。該模塊中使用的氣體傳感器基於MEMS技術,具有體積小,測量穩定性高的優點,並且比定性測量更適合定性測量。

特徵

  • 一個封裝上有四個完全獨立的傳感器元件。
  • 具有檢測一氧化碳(CO),二氧化氮(NO2),乙醇(C2H5CH),揮發性有機化合物(VOC)等多種氣體的能力。
  • 定性檢測,而不是定量檢測。
  • 體積小巧,易於部署。

使用之前,需要對傳感器進行預熱以達到內部化學平衡。預熱電壓與其加熱電壓VH一致。並建議如下的存儲時間和相應的預熱時間: 

存儲時間如何影響此傳感器的建議預熱時間?

儲存時間 建議的預熱時間
不到1個月 不少於24小時
1-6個月 不少於48小時
6個月以上 不少於72小時

這與我們以前的多通道氣體傳感器有何不同?

注意事項

  • 模塊應避免放置在揮發性矽化合物蒸汽中,否則將導致靈敏度降低且無法恢復。
  • 模塊應避免暴露於高濃度的腐蝕性氣體(例如H2S,SOX,Cl2,HCl等)中,否則將被不可逆轉地損壞。
  • 請勿將模塊放在水或冰中。
  • 模塊上電後,傳感器在此過程中會加熱到一定程度,這是正常現象。
  • 用戶必須在開始測量氣體之前對模塊進行預熱。

Grove – Multichannel Gas Sensor v2

Description

Worried about not recognizing the gas around your workplace or other surroundings and environment? Here comes the excellent solutions we offer!  Grove – Multichannel Gas Sensor V2 has 4 measuring units, each of them is sensitive to various kinds of gases, which means you are able to get four sets of data at the same time. And different sorts of gases can also be judged by these four sets of data. The gas sensor used in this module is based on MEMS technology and has the advantage of being in a small size with considerable measurement stability and is more suitable for qualitative than quantitative measurement.

Features

  • Four fully independent sensor elements on one package.
  • The ability to detect a variety of gases, besides Carbon monoxide (CO), Nitrogen dioxide (NO2), Ethyl alcohol(C2H5CH), Volatile Organic Compounds (VOC) and etc.
  • Qualitative detecting, rather than quantitative.
  • Compact size for easy deployment.

Specifications

MCU STM32F030
Interface 0x55
I2C address 3.3V~5V
Onboard Gas Sensors GM-102B; GM-302B; GM-502B; GM-702B

Note

Before using it, the sensor needs to be preheated to achieve the internal chemical balance. The preheat voltage is consistent with its heating voltage VH. And the storage time and corresponding warm-up time are recommended as follows:

How Does Storage Time Affect The Recommended Warm-Up Time of This Sensor?

Storage time Recommended warm-up time
Less than 1 month No less than 24 hrs
1-6 months No less than 48 hrs
Over 6 months No less than 72 hrs

How Does This Differ From Our Previous Multichannel Gas Sensor?

Cautions

  • The module should avoid being placed in the volatile silicon compound steam, or it will cause the sensitivity to be reduced and irrecoverable.
  • The module should avoid being exposed to high concentrations of corrosive gases (such as H2S, SOX, Cl2, HCl, etc.), otherwise, it will be irreversibly damaged.
  • The module should not be placed in water or ice.
  • After the module is powered on, the sensor will heat up to a certain degree during the process, which is a normal phenomenon.
  • Users MUST preheat the module before starting to measure gases.

Parts list
