High blood pressure, also referred as, hypertension could be a silent killer which increases the danger of diseases like heart attack, kidney disease, metabolic syndrome and blindness. It can also cause premature death. It's necessary to monitor the blood pressure continuously, so as to stop diseases and death. The normal method of pressure measurement uses sphygmomanometer with cuff which is not an effective method to monitor the blood pressure continuously. This paper involves a different method to estimate the pressure continuously and non-invasively. We employ a technique of determining pulse transit time (PTT) parameter from obtaining the Electrocardiogram (ECG) and photoplethysmogram (PPG). The PTT is time taken by the blood pressure waves to move from one point to another point of arteries. The PTT helps to estimate the blood pressure in unremitting manner. We implement this method through low cost and reliable embedded systems design to simultaneously measure the ECG and PPG signal. Those signals are further processed to determine the PTT by applying peak detection algorithms. The PTT is further used to estimate the blood pressure. The IoT helps to monitor blood pressure and heart rate through the android/web applications.
