GitHub ostaquet/ArduinoMQ131driver: Arduino driver for ...

If you put Vcc on the sensor and not on the heater, you could damage your sensor irreversibly. Sensor MQ131 requires minimum 48h preheat time before giving consistent results (also called "burnin" time) There are three different MQ131: a black bakelite sensor for low concentration of ozone (with WO3 sensitive material) a blue bakelite sensor for low concentration of ozone (with SnO2 sensitive ...

MQ131 Sensors Arduino Forum

· The heater needs 6V, not 5V as in the example (the example is for an other sensor). So you really have to use 6V. These sensors are cheap and do fluctuate, so using 5V makes it even worse. Do you actually get a reading from the sensor, or did you use the wrong input and is your input floating ? The preheat time is 24 hours. Did you already had ...

: SainSmart MQ131 Ozone Gas Detection Sensor ...

The much cheaper MQ 2 sensor I had right next to it in an ozone test chamber. Maybe they mislabeled the one I got sent or that dent caused the sensor to turn in to an MQ 2, but I definitely did not get a proper MQ 131 sensor. Read more. 3 people found this helpful. Helpful. Report abuse. James. out of 5 stars Easy to us. Wish they were less expensive. Reviewed in the United States on June ...
