AirSafe is a Houston-based project that provides both live and historical readings of pollutant levels in the atmosphere.

Live Data
The top half of the display shows your distance to the nearest gas sensor, along with the live reading from that sensor. AirSafe then helps you interpret what that pollution level means by showing safety thresholds.

Sensor Map
A map shows all of the sensor locations as pins with the measured pollution level at that sensor.

Historical Data
A graph of a sensors past observations can be pulled up by tapping on the corresponding marker on the map.


About the Project
The AirSafe app is part of the community-facing end of a collaborative project by Rice University. The project hopes to provide useful, high granularity data about the gases in the atmosphere to both researchers and members of the community.

Note that the data in this app focuses on the Houston area.
