Internet of Things for Heart Rate Monitoring System
AbstractTechnological innovations in the field of medical science has assumed an imperative part in disease prevention and diagnostic. One such progression is heart rate monitoring system. Heart rate is an important health parameter that is connected to the human cardiovascular system. Change of blood can be identified through an optical detecting system placed around the fingertip or on ears. The signal can be amplified and is sent to nodeMCU and then processed with the help of serial port communication. The pulse can be fingered from those areas where the artery is close to the skin. It is based on the principal of photophelthysmography (PPG) which is non-invasive method of measuring the variation in blood volume in tissue using a light source and detector. This paper describes a method of measuring the heart rate through a fingertip and show the heart beat on the LCD screen and sent the notification by Email and SMS and also stored the data using Google sheets.
Submission of an original manuscript to the Journal of Computing Technologies and Creative Content (JTeC) will be taken to mean that it represents original work not previoussly published, that it is not being considered elsewhere for publication. All submitted articles that are published by JTeC cannot be published anywhere by the authors unless with the permission by JTeC Editors. JTeC reserves the right to the publications of the articles it published, and reserves the right to reuse the articles elsewhere for academic purposes, while still retaining the names of the original authors with the original articles.
JTeC takes the stance that the publication of scholarly research is meant to disseminate knowledge and in a not-for-profit regime, benefits neither publisher nor author financially. It sees itself as having obligation to its author and to society to make content available online now that the technology allows for such possibility.
