GM-702B MEMS Carbon Monoxide (CO) Gas Sensor – Advanced MEMS CO Detection Module
The GM-702B MEMS Carbon Monoxide Gas Sensor is a high-precision gas detection component engineered for reliable and rapid detection of carbon monoxide (CO) in residential, commercial, and IoT applications. Built on cutting-edge MEMS (Micro-Electro-Mechanical Systems) technology, this sensor delivers excellent sensitivity, stable performance, and long-term reliability in a compact and energy-efficient package — making it an ideal choice for modern safety devices, air quality monitoring systems, and smart connected solutions.
Carbon monoxide is a colorless, odorless, and highly toxic gas typically produced by incomplete combustion of fuels from sources such as gas stoves, heaters, car exhaust, and generators. Because CO cannot be sensed by human senses, highly accurate sensors like the GM-702B are essential for early detection and protection against carbon monoxide exposure.

Ideal Applications
The GM-702B MEMS Carbon Monoxide Gas Sensor is suitable for a wide range of applications that require precise CO monitoring and safety:
- Home carbon monoxide alarm systems
- Indoor air quality (IAQ) monitors
- Smart home safety devices
- Portable CO detector and warning devices
- HVAC and ventilation monitoring systems
- IoT and connected sensor platforms
- Embedded electronics and microcontroller projects
- Educational and DIY electronics kits
How the GM-702B Works
The GM-702B uses MEMS technology — a miniaturized mechanical and electronic sensing structure — to detect changes in carbon monoxide concentration. When CO molecules interact with the sensing surface, the device’s electrical characteristics change proportionally to the gas level. This change is converted into a stable analog output that can be easily read by microcontrollers or signal processors.
MEMS gas sensors offer high accuracy, fast reaction times, superior repeatability, and low power consumption compared to traditional sensing technologies, making them a premium choice for modern CO detection solutions.
