Eupnea is a wearable, Arduino-based respiration monitor that collects the user’s breath data and transmits it via BlueTooth to their Android device for display and storage. The word, “eupnea,” is of Greek derivation and means good or healthy breathing. In addition to allowing the user to visualize their breathing on the screen, the Android device also geolocates the samples. Although this prototype does not yet store the data on the phone, the next iteration will allow the user to save and extract their geolocated breath data so that they can create maps of their breathing activity.

Eupnea was built using Processing , Arduino, and the Android SDK.
