How would you know how to calibrate them without a known-good reference device ? How would you know how much to calibrate for humidity anyway ?
FWIW, I've been using weewx to save my PurpleAir data for over 27 months of data into a separeare db if you guys want a copy in order to do some checking of whether your correction algorithm lines up with what you 'think' PurpleAir is doing when they calculate AQI that they report. Email me if you want a copy. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
