Breath Analyser

We wrote firmware and developed an android and iOS app for the breath analyzer. The hardware measure and sends air pressure to the app. It also gives user feedback with LEDs. The app measures air pressure to analyze breathing pattern. It also provides visual indication on app.

Firmware:

1. Wrote firmware algorithm to convert pressure into breathing pattern.
2. The pressure data was sent to the app for further processing
3. Received commands over BLE from the app to display LED status

Mobile App

1. Developed cross platform app with React native for iOS and Android.
2. The app handled user and device configurations
3. The app process pressure data from BLE and generated patterns for LED indication on the device.
