Grove - Multichannel Gas Sensor v2 - Besides CO, NO2, C2H5CH, VOC - MEMS gas sensor

Grove - Multichannel Gas Sensor V2 provides a stable and reliable gas detecting function under the circumstances of any other four sorts of gases. It can detect a variety of gases, besides Carbon monoxide (CO), Nitrogen dioxide (NO2), Ethyl alcohol(C2H5CH), Volatile Organic Compounds (VOC), etc. 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 Specifications MCU STM32F030 Interface Grove I2C I2C address 0x08 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 How Does This Differ From Our Previous Multichannel Gas Sensor?

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. What is Grove? Grove makes it easier to connect, experiment, and simplify the prototyping process. No jumpers or soldering required. We have developed more than 300 Grove modules, covering a wide range of applications that can fulfil a variety of needs. Not only are these open hardware, but we also have open-source software. Note For all Grove users (especially beginners), we provide you with the guidance of operation.
