MQ2 Reading different gases Sensors Arduino Forum


6/5/2021· MQ2 Reading different gases. Hi all. I am using this code example from Sandbox Electronics to read from the MQ2 gas sensor. However, all my readings are 0. If I use a simple analog reading on the specific pin, I get the expected analog values from 0 to 1023, usual values around 250, and if I expose it to gas for example goes up to 1000.

Il faut donc un capteur d''ozone MQ131 (nous allons bientôt publier une application qui permet des mesures précises et stables avec des capteurs de gaz MQ). Et une concentration et un temps suffisants doivent être utilisés pour inactiver les virus, mais sans exagérer, et garder l''air en mouvement, avec un ventilateur, afin d''avoir la même concentration en tous points de la pièce.
