MG811 CO2 Sensor Module - High Sensitivity, Analog Output for CO2 Detection

The MG811 CO2 Sensor Module is designed to detect carbon dioxide (CO2) concentrations in the air, providing an analog voltage output that is proportional to the CO2 level. This sensor module is based on the MG811 gas sensor, which has high sensitivity to CO2 and can be used in various applications such as air quality monitoring, HVAC systems, and greenhouse automation.

The module is equipped with an onboard signal conditioning circuit that amplifies and stabilizes the sensor output, making it easier to interface with microcontrollers like Arduino, ESP32, and Raspberry Pi. The sensor is highly selective to CO2 and features low cross-sensitivity to other gases, providing accurate and reliable results. The onboard potentiometer allows for sensitivity adjustment to suit different applications.
