Is there a way to get the location data from an offline sensor?

Data
1

I am a new user of PurpleAir.
I have mounted a PA-II-SD in a location where it does not have WiFi. I plan to download the data from the SD card at regular interval. I checked the data guide and found that I can download the CSV file with appropriate headers. But none of the headers seem to indicate the location of the sensor.

Is there a way to download the sensor location (longitude/latitude) from offline data?

As far as I know there isn’t.

But there also really isn’t a need for it to log location into the CSV files.
It doesn’t have a GPS on it to find the coordinates, and you probably aren’t moving constantly.

You can find the longitude/latitude by dropping a pin on Google Maps where you placed the sensor. To keep the location recorded on the SD card, you could probably paste the coordinates into Notepad and save them as a TXT file to the card.

Let me know if your PA-II-SD doesn’t consistently record data to the SD card. I’ve been having some issues with the PA-II-Flex…

Thanks EKauffman!
I guess I will use Google Maps to get the long/lat.

Yes, my sensor does seem to consistently record data to SD card. Both channels give very close measurements to one another.

does your sd card give PM reading in micrometers?

The sensor doesn’t have a GPS to track it’s actual location, but you can use the PurpleAir API to retrieve the latitude and longitude that were set for the sensor during registration (the map location of the sensor).
