DFRobot Gravity Analog CO2 Sensor MG811 for Arduino - Module Only
The DFRobot Gravity Analog CO2 Sensor MG811 is an Arduino-compatible module designed for measuring carbon dioxide concentration. It outputs an analog voltage inversely proportional to CO2 levels and includes a digital threshold alarm, making it suitable for environmental monitoring and educational projects.
Features
- MG-811 sensor core with high sensitivity and selectivity for CO2
- Analog voltage output decreases as CO2 concentration increases
- Onboard potentiometer for setting digital alarm threshold
- Internal power-boosting circuit provides stable 6V heater supply
- Gravity 3-pin interface for easy plug-and-play connection with Arduino

This CO2 sensor module utilizes an MG-811 electrochemical sensing element, known for its good selectivity to carbon dioxide with reduced cross-sensitivity to alcohol and carbon monoxide. An integrated heating circuit maintains the sensor at its optimal operating temperature, ensuring stable performance and low dependency on ambient humidity and temperature fluctuations.
The onboard signal conditioning circuit amplifies the sensor’s weak output to a readable analog voltage range. The module is designed for seamless integration with Arduino and other microcontroller platforms via its standard Gravity 3-pin connector, simplifying wiring for air quality monitoring, HVAC control, and indoor environmental studies.
