Measure CO2 with MQ-135 and Arduino Uno - Rob's blog

Jan 04, 2017· The next morning ppm was down to 500 according to the NETATMO, but the arduino showed a ppm of 600. I change the RZERO to 819 and the arduino also showed 500. This is no good of course, so something must go wrong in the calculations in the MQ135 library. Or I am using a MQ-135 sensor with a bad response curve.
