MG811 Carbon Dioxide CO2 Sensor

Easily measure carbon dioxide (CO2) levels with this Arduino-compatible sensor from PMD Way. Based on the MG811 sensor, the output voltage is inversely proportional to the amount of CO2 in the area.

You can use this sensor with any microcontroller that has an ADC range of 0~5V DC. The module features an onboard heater to ensure the sensor performs at the optimum level. 

Please note that this sensor is not intended for or certified for use in life-support or medical equipment. PCB color may vary.
