MQ 131 when detecting ozone Sensors Arduino Forum

May 06, 2021· Hi, There is two ways of using the MQ131: directly the sensor itself (bare / naked sensor) via a module I used to have a module and I remove the sensor from the module because the documentation doesn’t exist. The two important things are: 1. You have to preheat the sensor for 48h at 5V to have consistent result. 2.
