Calibration and MQ135 Library
05/09/2015 at 15:35 • 1 comment

The hardest part of this project was calibration. While working on calibration I had found a great contributor of the Sniffing Tricket by Georg Krocker. In his project he details how to calibrate the sensors and also gives a GREAT library for the MQ135. https://github.com/GeorgK/MQ135
