I've been trying to collect mobile transect data using the PurpleAir II SD. Since I'm driving or cycling around with my sensors, I am completely dependent on storing the data locally on the SD card. Unfortunately, I have seen really poor data recovery so far... It's usually a 50/50 chance that I'll actually have any new data on the card.
Has anyone experienced this, or know of any solutions? Are there any notable alternatives to using the PurpleAir?
Thank you,
Philip
