8月31日 的 AQ Alert 應用程式分析

Locate Purple Air sensors important to you, and add them to your watch list. Once a sensor is in your watch list, you can set alerts and receive push messages when air quality reported by the sensor crosses key thresholds, or get notified when a sensor goes offline. The Purple Air "community scientist" sensor network provides data about air quality to researchers and the public. Using AQ Alert, you can stay updated without checking the Purple Air map.
