CO2 Monitor - Arduino Project Hub

The CO2 concentration is calculated from the measured resistance and the temperature/relative humidity correction. It may be written as: CO2 = 410*ppm*(Rs/f_RH_T / Rs410/f_RH_T_410)^b. Where the exponent b is equal to - according to Mad Frog. And where Rs410 is the sensor resistance measured in clean air (410 ppm of CO2) and f_RH_T_410 is ...

Problem with MG811 CO2 Sensor : arduino

Problem with MG811 CO2 Sensor. Close. 1. Posted by 2 days ago. Problem with MG811 CO2 Sensor. I tried the code below, and it works. However, when I am about to unplug and re-plug the Arduino, the value is no longer accurate. It received both a high value more like 20000+ and a negative value. What is the reason for this? When I press the Arduino's built-in reset button, the value will be ...
