This project has been developed for the Cyber Physical System course at the University of Turku.
During the mentioned course, we were introduced to microcontroller boards like Arduino Uno, and were assigned the task of a practical project that needs to include some kind of wireless communication, preferably related to health care.
Our group decided to create HeartBuddy, a Arduino Uno based device that monitors the heart rate of a person and triggers emergency messages via bluetooth on a connected Android phone. This means that the project consists of two parts:
- The device itself called HeartEmergencyKit (this repo)
- An Android application to handle the transmitted data: Source
If the Android application is connected to the device, it will constantly receive & display the heart rate and emergency notifications, after which the Android phone sends a text message with the current heart rate and geolocation information to pre-defined care givers.
This code is based on the example code of the pulse sensor by WorldFamousElectronics, which brings most of the heart rate specific functionality.
- Arduino Uno board
- Sensors/Actuators: Pulse sensor, Bluetooth sensor, Button, LED
Connect the sensors on the following pins:
- Pulse Sensor: Analog 0
- Bluetooth Sensor: Digital 10 (Tx), Digital 11 (Rx)
- Button: Digital 6
- LED: Digital 8
