I’m experimenting with the Enviro+ board and was kindof hoping it would allow me to measure directly concentrations of various gases. However, it seems it’s going to require a bit more magic to get it.
I was wondering if someone in here knows about the proper usage of the sensor. Or maybe even a code sample demonstrating it. To this point I am clueless about the usage and the interpretation of the figures.
It clear now it’s not just one api call to get the final value. Apparently repetitive calls are required until readings “converge”. Is this just reading the sensors until the differences are close to zero ?
This conversion is supposed to be a baseline, according to the sensor’s specs. But from there, how does one interpret the resistance readings to concrete/approximate gas concentrations ?
Any hint is welcome ! :-)
