Airwyn

Alerta y monitorea la calidad del aire (AQI) de PurpleAir y los sensores de la EPA de EE. UU. (AirNow).

Airwyn lets you monitor a single public PurpleAir sensor or US EPA (AirNow) sensor. You can get ongoing silent notifications, or choose to get an audible alert when air quality index (AQI) goes up or down. This can let you make important decisions for your safety and health -- like when to go inside, and when to open or close windows.

A map gives an overview of AQI in your neighborhood, and lets you pick a PurpleAir or US EPA sensor to monitor. A simple color-coded graph shows how the air quality has changed over the last few days for your chosen sensor.

AQI conversion formulas from US EPA, LRAPA, and AQandU are supported.
