Fixing the map’s location for your sensor is no problem at all.
You first want to navigate to the email you received when you first registered the sensor. In that email you will be presented a link to “modify registration.”
Once on that page, you can make any needed changes. In the “Map Location” section, you can drag the red pin to the correct place and save the changes by clicking the “Register” button. Another method is to enter the relevant latitude and longitude and verify the pin placement.
Here is our guide on updating the registration information on your sensors registration: Update Registration Details.
If you cannot locate the registration email that was sent you can access the registration page directly. The registration page can be accessed here: Register to place your sensor on the map | PurpleAir.
