NGW-1pc Grove - Multichannel Gas Sensor v2 - Besides CO, NO2, C2H5CH, VOC - MEMS gas sensor
- Features
- Independent measurement units ensure accurate results: encapsulates four MEMS sensor devices completely independent
- High-performance gas sensor: high gas sensitivity and high measurement stability
- Ability to monitor multiple gases: besides carbon monoxide (CO), nitrogen dioxide (NO2), ethanol (C2H5CH), volatile organic compounds (VOC), and more
- Qualitative detecting, rather than quantitative.
- Compact size for easy deployment.

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 which 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 of a small size with considerable measurement stability and is more suitable for qualitative than quantitative measurement.
Application
Indoor Air Quality Monitoring
carbon monoxide gas leak alarm
Exhaled gas detector
indoor smoke alarm
In-vehicle safety: car ventilation control; gasoline vapor detection; alcohol breath test
MCU STM32F030
Interface Grove I2C
I2C address 0x55
Output voltage 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
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.
Note
For all Grove users (especially beginners), we provide you with the guidance of operation. Please download and read through Sensor - Gas and Seeed Gas Sensor Selection Guide before your using the product.
