Project Description

Smart Al-Test is an IoT breathalyzer system that connects a BLE-enabled device to a web application. Users can securely sign in, pair the device, perform a breath test, and view stored results under their own account.

How does it work?

The breathalyzer device measures a breath sample and sends the reading to the web app over BLE. The web app displays the result and stores it in the database so the user can review their history later.

Key Features

  • •User Authentication: Secure sign-up and sign-in functionality.
  • •Device Pairing: Easy pairing of the breathalyzer device via BLE.
  • •Breath Test Functionality: reliable alcohol level measurement.
  • •Data Storage: Results are stored in a database linked to user accounts.
  • •Responsive Web App: Data is accessible on computer and mobile devices for convenience.
