geschmierer and vcoder. Thank you both very much for your work on this. This is the most helpful thing I’ve found on the Seeed Multichannel Gas Sensor so far!
Your code attached above makes a lot of sense until I get to the part where you’re calculating PPM using the Log10 functions. Can you help me understand that part? It looks like you use slightly different values for each of the sensors. But I’m unclear why Logs are required for calculating PPM. Is it just part of converting the voltage to an actual value? If so, where did you get the numbers you used in the equations?
Thank you so much for your help on this.
