Hello, I’ve been following the Purple Air sensor network for a while now.

I’ve tried several times to download the historical data series with a 30-minute average for all the data that the sensor “MPPA\_MRT\_01\_2ndFloor” has captured. This sensor has been operational since 2020, and I want the historical series with a 30-minute average from that period to the current moment. I can download the annual average for the entire historical series, but for this specific 30-minute interval, which is my interest, the platform limits me to approximately 3 days.

Does anyone have a solution?

Hi @Augusto_Gabriel

The PurpleAir map only shows recent data. To access more historical data, which it sounds like you want to do, you will have to use our [API](https://api.purpleair.com/). It is important to note that the API is now a paid service, however, all new users are automatically supplied with one million points.

We also provide the [Data Download Tool](https://community.purpleair.com/t/purpleair-data-download-tool/3787), which makes receiving data from the API much simpler.
