Overview

A IoT biometrics reading device, which utilizes the Amazon AWS IoT service to communicate with a python-based desktop client.

The core concept is a IoT biometrics reader, which utilizes a Arduino UNO R3 with a e-Health sensor shield and Pulsioximeter sensor. It connects to an Arduino Yún which transmits the collected data to the AWS IoT platform. Furthermore a python based client, independent from the Arduino, provides access to the uploaded data and enables data upload requests. Conceptually a healthcare providerwould be able to remotely monitor patient biometrics, by being able to request/analyse biometric data in tandem with direct patient e-communication. This would reduce the amount of time spent both by patients and healthcare providers in both initial diagnosing and extended non-intensive patient monitoring.

#Device Functions

• Red LED turns on when a connection is successfully established to the AWS IoT service.
• Yellow LED turns on when there's a pending reading request from the python client.
• Green LED turns on when data is being transmitted to the device shadow.
• RGB LED turns blue when device is in Sleep Mode.
• RGB LED turns green when the switchbutton is pressed, indicating that device is active.
• RGB LED turns cyan when the pulsioximeter is transmitting data.

#Client Functions The client has the following options:

• Request biometric reading.
• Cancel biometric reading requests.
• View latest biometric reading.

Setup

1. Download and install 2 versions of the Arduino IDE, 1.6.0+ for the Arduino Yún and 1.0.1+ for the Arduino Uno R3. https://www.arduino.cc/en/Main/Software>.
2. Download and install the AWS-IoT-Arduino-Yún-SDK for the 1.6.0+ IDE.
3. Download and install the e-Health Library for Arduino for the 1.0.1+ IDE.
4. Load the "Arduino-Yun-Sketch" onto the Arduino Yún.
5. Load the "Arduino-Uno-Sketch" onto the Arduino Uno R3. (6). Make sure the Arduino Yun is properly set-up and configured to a wifi network.
