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.

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

Precautions

• The module should avoid being placed in the volatile silicon compound steam, or it will cause the sensitivity to be reduced permanently.
• 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, see table for information.
