IOT based Remote Heartbeat Monitoring

Deployment of Internet of Things (IoT) has made sensors smarter so that they can interact, collaborate and share experiences. IoT not only reduces human intervention but also assists in taking timely decision. IoT based telehealth is a new paradigm in the health-care industry. Proposed work is an implementation of IoT based heartbeat monitoring system. Proposed method is tested with a photo phlethysmography sensor interfaced to a micro-controller. Micro-controller monitors the heart beat sampling rate and then transmits discrete values over ESP8266 Wi-Fi module. Thingspeak has been used as the remote cloud server for secure data storage and access. Key contributions of the work are, firstly enabling secured cloud platform to keep track of heart beat and secondly facilitating automatic alert system in case of emergency. Besides this, the proposed set up supports made to required sampling rate and investigation. Results have been produced for different acquisition conditions. An analysis scenario, with minimum and maximum thresholds, which can send alert message if the heart beat rate goes beyond the range has been manifested and tested. Proposed method can be deployed for secured and continuous monitoring of heart beat while customizing the analysis.
