HRV (Heart Rate Variability) acts to be a predictor for cardiovascular diseases. In this paper, the authors propose a low-cost and easy to Remote HRV Monitoring System based on the Internet of Things (IoT) technology for borderline Hypertensive patients in the proposed system, it continuously monitor the health parameters such as HRV (Heart Rate Variability), pulse oximetry and body temperature. These parameters are derived using sensors. Arduino transmits patient data to the server the caretaker and doctors are intimated through SMS and surrounding peoples with buzzer for providing adequate medical help in case of emergency situation and also doctor can provide remarks about the condition to the patient through this system. Now there are no HRV and Pulse oximetry monitoring the alert for patients. By doing so all the ideal traits of a ‘IoT health care system for remote monitoring’ in terms of low cost, easy to use, and secure that serves in saving lines.
