Pulse Oximetry and IOT based Cardiac Monitoring Integrated Alert System

In this project, we offer a modern day, embedded Systems & IoT based solution for continuous and non-invasive measuring of the cardiac values using an upcoming technology known as pulse-oximetry. This technology uses a medical sensor creating a photoplethsmogram from which we can detect the oxygen saturation level and variations in blood volume in the tissues. This analog waveform is further processed using hardware filters to obtain heart rate and SpO2 values.In case the cardiac values are found to deviate away from the set thresholds, an automated emergency alert system is triggered .
