Hi everyone,
I’m currently using the PurpleAir Zen – Air Quality Monitor and I’m wondering if it’s possible to increase the logging rate on the SD card to every second (1 Hz).
I’m a researcher and need higher-resolution data for analysis purposes. I could only find discussions and solutions for the PurpleAir Classic SD models (PA-II-SD), such as modifying the config.txt file or adjusting wiring, but I haven’t found any information or instructions for the Zen model specifically.
Has anyone successfully configured the Zen model to log data at a 1-second interval?
If so, could you kindly share the steps or whether it’s even supported?
Appreciate any help or guidance—thanks in advance!
Best regards
