30/12/2020· Re: How to operate MG811 CO2 Sensor on ESP32. Postby ESP_Jan » Wed Dec 30, 2020 1:20 pm. Hi os3n6c, based on the specifications the MG811 sensor requires ± 200mA for its operation. You will need to have a 6V power supply for this sensor or a voltage regulator. Feel free to post any followup questions.
MG811 CO2/Carbon Dioxide Sensor Module for Arduino This sensor module has an MG811 onboard as the sensor component. There is an onboard signal conditioning circuit for amplifying output signal and an onboard heating circuit for heating the sensor. The MG811 is highly sensitive to CO2 and less sensitive to alcohol and CO.
MG811 Calibration for the autoctrl board on Arduino (UNO) * This calibration is very simple, and so lacks accuracy for serious use. See this script as a gettingstarted solution. * The calibration relies on 2 points, at 400ppm and 1000ppm. The 400ppm is the assumed CO2 concentration in "fresh air".

06/05/2021· 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).
