Hi Bryce, and welcome! Have you seen this? Higher Logging Rate on the SD Card
The logging rate is something that can be altered on the device directly, and if you’re able to connect to a computer, you can get second-by-second readings. That said, the upload rate is effectively locked to 2 minutes, due to the realities of data storage and data consistency requirements.
If you have a specific use case you’d like to discuss, please email us at contact@purpleair.com. We have occasionally been able to make limited alterations in very specific use cases, but these alterations may require setting your sensor to “private.”
