IoT-Based Heart Rate Monitoring System

Technology has changed our world in all-round manner, starting from the food processing to our daily lifestyle and in our daily chores. Heart being the most important vital organ of the body needs special focus as most of its irregularities, if not all, are life threatening. The most common heart disease involves coronary heart disease, heart arrhythmia, and tachycardia. Through this project, we are presenting a new way of monitoring and detecting heart attack and various other diseases. The system uses principle of photophelthysmology which involves measuring the variation in blood volume in tissue using light and sensor that it contains. To pump blood through body, heart first contracts and forces blood that it has received through veins into arteries after mixing it with oxygenated blood. Then, it takes rest of few millisecond and pump blood back again thus creating a cycle. This variation is recorded by heart rate sensor and shown as output on mobile application. Each person has his own high and low value which he can set in application by default after getting professional consultation from specialist.
