Hi,
I just try to connect 7 sensors to an nano.
MQ-2, MQ-3, MQ-4,MQ-6, MQ-7,MQ-9, MQ-135
With sketch form robosensor https://forum.mysensors.org/topic/1595/mq2-sensor-w-airquality-sketch/2
I get data like MQ-7:1020 ,MQ135: 294, MQ-2:191
So it looks really good.
As i would like to have also the correct names an value names of the sensor and a correct calibration I think I should use a sketch like AirQuality-Multiple_Gas_Sensor1_4.ino
But I only see 3 of my 7 sensors in this sketch.
What would be a good sketch for my 7 sensors ??
Thanks
Jorg
