About this product
The MG811 sensor uses a solid electrolyte sensing element that changes its output voltage according to the CO₂ concentration. Because the sensor’s output voltage is very small, most MG811 modules include:
The sensor requires a warm-up period before providing stable readings.
•Adjustable digital alarm threshold.
•Suitable for microcontrollers such as Arduino , ESP32 , Raspberry Pi (with an ADC for analog input), and other embedded systems.
