Measure CO2 with MQ135 and Arduino Uno Rob''s blog

· 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 MQ135 sensor with a bad response curve. The next day I have tested the same with another MQ135, but the results were about the same. Wrong formula in the library
