Is there a way to change the frequency in which the PurpleAir collects data? It seems like it is preset to 2 minutes, can this be lowered to 1 minute?

Hi Bryce, and welcome! Have you seen this? [Higher Logging Rate on the SD Card](https://community.purpleair.com/t/higher-logging-rate-on-the-sd-card/3799)

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](mailto: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.”
