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 ...
