Associated Email vs. Owner's Email

Associated: This is the email address used by the buyer to complete the purchase of the sensor and is used as a reference. This email address is paired with the MAC address of all sensors bought in the same transaction and must be used as the Associated Email to register the sensor. This can be any number of emails but only one can be used when registering. The associated email address will get an email notification upon registering. If it is the same as the owner’s email address, only one email will get sent; if they are different, an email will get sent to both email addresses.

​Owner: The owner’s email address is put in when registering and is the email address typically of the person hosting the sensor. If you are logged into the PurpleAir map this is the email address the map uses as the owner, so when looking at “my sensors” you would use the owner’s email address to log in to the PurpleAir map. This makes it easy to move the sensor to another person and change the owner’s email. If it moves, and we archive the data, the owner’s email is removed and only the associated email(s) can register the sensor again while adding a different owner email.

Viewing private sensors:
If you’ve registered your sensor as private, you can log in to the PurpleAir map with the set owner’s email, connect to our servers, and view the graphs and your sensor from anywhere. This email will need to be a Google-associated email as that is the mechanism we currently use. You also have access to your sensor’s data, allowing you to download historical information. Alternatively, you can view the real-time data on the sensor’s IP address.

Another option is to use the “view it here” link provided in the registration confirmation email, which was sent to the Associated and Owner’s Email addresses indicated on the registration form. This link can also be bookmarked and/or sent to others with whom you’d like to share your private sensor.

Tip: If you are logged into the map, you must ensure that the “my sensors” option is checked in order to see your sensors.
