3.9. WiFi connection
WiFi network credentials (name and password) are provided to the sensor
during the Cloud Dashboard provisioning process. Provisioning is done on
the mobile app (iOS and Android), as outlined in the Cloud Dashboard
manual. Once connected, the sensor saves the WiFi credentials to
memory. The sensor automatically detects and connects to saved
networks. More networks can manually be added to the ObservAir’s
memory using the ObservAir Desktop application or serial commands.
