can arduino co2 sensor do

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 be measured.

Arduino + CO2 sensor MG811 - Interfacing - Arduino Forum

06/05/2021· Yes, you do need 6V to run the heater in the Co2 sensor, the arduino will not supply this so you must get the sensor it's own voltage regulator. I have the circuit set up and it works perfect. I just need to code and calibrate. Here soon in the next few days I'm going to set up a page on I'll come back and post a link when it's finished. system. April 16, 2021, 3:34pm #10. it ...

Precalibrated CO2 sensor - Sensors - Arduino Forum

06/05/2021· Could you point me on some calibrated and easy to use CO2 sensor, preferably with some digital interface for long distance reading? What I'm trying to do is to make cheap device that measures temperature, humidity and CO2 (air quality) on 3 points in an apartment with just one Arduino. For temp/humidity I'm thinking to use DHT22, nice, cheap and 1-wire sensor (for up to 20m distance).
