Hi author! Nice write up and good analysis. However I think you missed something in the analysis. The sensor is only accurate to +-20uG/m^3 this also means it can never reach a reading of healthy air according to the WHO specs... I think that is a bigger issue that the traffic light UI. Apologies for picking on this issue. I am very thankful you took the time to create this article and look at the all the specifications.
