ESTIMATION OF HEART RATE USING SMART PHONE CAMERA

This research paper introduces an app designed to monitor heart rate using photoplethysmography (PPG) with a smartphone camera. The app was developed using the Dart language and the Flutter framework, in Android Studio. Notable features of the app include real time pulse detection, heart rate measurement and seamless data storage in the Firebase cloud platform. By utilizing the imaging capabilities of smartphone cameras this mobile app captures PPG signals allowing for intrusive monitoring. The combination of Dart language and Flutter ensures a smooth and responsive user interface for a user experience. Additionally, this app integrates with Firebase as a scalable service for storing data. This integration enables users to access and review their heart rate data across devices effortlessly. With real time synchronization provided by Firebase users can always have up to date information on their health. This study adds to the growing field of mobile health apps by showcasing how Dart and Flutter can be used to develop heart rate monitoring apps that’re both reliable and user friendly. By integrating Firebase, the data storage system becomes more accessible and dependable which opens up opportunities, for healthcare approaches based on data analysis.
