Real-time Heart Rate Monitor and Dashboard in Android

A tutorial outlines the creation of a simple heart rate monitoring application for Android, which captures heart rate data using the phone's camera and streams it in real time to a monitoring dashboard. The app utilizes an image processing algorithm to detect the red component in the user's finger image, determining heart rate by calculating the variation in average red color intensity. Data is streamed using PubNub's data streams to a dashboard built with Material Design and the PubNub JavaScript SDK, which visualizes and allows retrieval of historical readings. Although inspired by wearables like Oura Ring and Apple Watch, the app serves educational purposes and is not intended for medical use, with plans to develop a similar tutorial for iOS.
