MQ 131 Sensor
-
@AnneFR by design, it wont, the MQ are $2 value and work n accuracy for this value.
They analyze particles of a certain size, that the maker/wholesaler says he tested it for, but it does not mean it will react only to this one.
I always use the broken perfume bottle that made all my MQ (at that time 3 different running on a mega) peak because my daughter broke in a bathroom a bottle of perfume and the air was saturated with particles.
Make your tests but don't rely on a $2 sensor.

Hello Epierre, I'm working in a proyect and i'm using MQ131 sensor, but I have a problem with the Arduino Code. I've seen the page (https://github.com/empierre/arduino/blob/master/AirQuality-Multiple_Gas_Sensor1_4.ino) but I have a problem because my sensor readings are 0. if you would be so kind, could you send me only the code of sensor MQ131 ??. Thank you very much!!
