Carbon Dioxide Sensor -

The carbon dioxide gas sensor measures gaseous carbon dioxide levels by detecting the quantity of IR radiation absorbed by carbon dioxide molecules. The sensor employs a hot metal filament that acts as an IR source to generate IR radiation. The IR source is located at one end of a sensor tube, and another end is provided with an IR sensor.

How to use MG811 - Sensors - Arduino Forum

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).

How does an NDIR CO2 Sensor Work? |

The band of infrared radiation is very close to the absorption band of CO2. As a result, the amount of light radiation that is absorbed by the CO2 molecules is proportional to the amount of carbon dioxide in the gas sample. However, since low levels of CO2 do not absorb much light, a long tube is needed before the effect can …
