AQ Finder


The AQ Finder, short for Air Quality Finder describing the application domain of air quality sensors, is an Android application that allows users to discovery contents of a Sensor Instance Registry (SIR) (provided through the SIR and Open Search interfaces) in a simple to use Android client.

A scientific publication on the topic is available: Discovering the Sensor Web through Mobile Applications by Theodor Foerster, Daniel Nüst, Arne Bröring and Simon Jirka.

ALERT! The development is continued as a 52°North Project: Finder.
