Dear Users,

I would like to know how to get a list of PA monitor(s) operated in the past to get its data for its operation period? For example, if today (3/10/2023) I query a list of monitors in geographic domain and get all operational PA monitors list but not those which were shutdown in the past or not in operation.

I appreciate your insight on this.

Thank you!

@Zuber_Farooqui I know that you can navigate to [https://map.purpleair.com/](https://map.purpleair.com/). Zoom into the area that you are interested in. Then open your browser’s developer tools. A quick google like `Open Google Chrome Developer tools` should help.

Look at the circle, it should list how many sensors were updated. it’ll also show how many are outdoors/indoors.

Now what I don’t know is the ability to know “how many were shutdown” since the last time data as checked.

I would suggest reaching out to `support@purpleair.com` for more help. In fact, I would suggest that a feature they could add to their [http://api.puprleair.com](http://api.puprleair.com)
