can carbon dioxide sensor module zero

CO2 Sensor Calibration: What You Need to Know |

Zero calibration is based on the idea that if you show the sensor/device a 100% concentration of an alternate gas than it is measuring, the sensor/device should read absolute zero. By following this method of calibration, the user is flooding the sensing chamber with the alternate gas and driving out any trace amounts of the original gas.

How to use MG811 - Sensors - Arduino Forum

May 06, 2021· Hi. I got the sensor MG811 that senses carbon dioxide, you can see an image of the sensor here I googled to use that sensor properly but i have doubts about the wiring with arduino and the proper way to calibrating. So, i got think i can got the data from AOUT pin, but i really don't know if i can use the 5V pin from arduino to connect in vdd or i need another source (around 12V).
