Using the oxygen sensor to tell if it's anaerobic or not makes sense, what sensor do you use for oxygen and how accurate is it over time? Does it have to be calibrated often?
And can you talk more about the role of TVOCs in anaerobic conditions? Wouldn't oxygen be enough?
Thanks!
We opted not to use oxygen sensors because they tend to be less reliable, require frequent calibration, and are significantly more expensive. Instead, we focus exclusively on TVOCs, as the technology is more advanced and offers a broader view of compost activity. During our early design stages, we found TVOCs correlate well with microbial activity, much like oxygen, while also capturing changes in the pile that oxygen levels alone might not immediately reveal.
