MQ 131 when detecting ozone Sensors Arduino Forum

· The two important things are: 1. You have to preheat the sensor for 48h at 5V to have consistent result. 2. In order to compute the ppm/ppb, you have to calculate the Rs/R0 and apply the sensitivity curve on it. Just check my lib on https:///ostaquet/ArduinoMQ131driver, you will find useful information in the code ;) Kind regards, Olivier
