Seeed Studio Studio Grove Multichannel Gas Sensor v2 - GM-102B/302B/502B/702B MEMS Sensors w/ STM32F030 & I2C Interface
The Seeed Studio Studio Grove Multichannel Gas Sensor v2 is a compact MEMS-based module featuring four independent gas sensing elements (GM-102B, GM-302B, GM-502B, GM-702B) for qualitative detection of CO, NO2, VOCs, and alcohol. It integrates an STM32F030 MCU and communicates via a Grove I2C interface (address 0x55), making it compatible with 3.3V/5V Arduino, Raspberry Pi, and other microcontroller platforms.
Features
- Four independent MEMS gas sensing elements (GM-102B, GM-302B, GM-502B, GM-702B) on a single package.
- Qualitative detection of multiple gases including CO, NO2, VOCs, and Ethyl Alcohol.
- Integrated STM32F030 microcontroller for onboard signal processing and data management.
- Standard Grove I2C interface (address 0x55) for easy plug-and-play connectivity.
- Wide 3.3V to 5V operating voltage range for broad microcontroller compatibility.

The Grove Multichannel Gas Sensor v2 employs advanced MEMS (Micro-Electro-Mechanical Systems) technology to house four distinct gas-sensitive elements within a single, compact module. Each sensor element is tuned to respond to different gas types, enabling the module to provide a qualitative profile of the ambient air composition rather than precise quantitative concentrations. This makes it ideal for applications requiring gas presence detection, pattern recognition, or relative air quality assessment.
The onboard STM32F030 microcontroller handles sensor signal conditioning, data acquisition, and I2C communication, simplifying integration with host systems like Arduino, Raspberry Pi, ESP32, or other development boards. The module’s design prioritizes measurement stability and repeatability in a small form factor, suitable for deployment in portable devices, environmental monitoring stations, and smart home systems.
